    Cataracts are the second most prioritized eye disease in the world. Cataracts are an expensive treatment because surgery is the only method that can treat the disease. This study aims to analyze the cost effectiveness of each operating procedure. Specifically, phacoemulsification and Small Incision Cataract Surgery (SICS) with Disability-Adjusted Life Years (DALYs) as the effectiveness indicator is used. This study is an observational analytic study with a prospective framework. The sample size is 130 patients who have undergone phacoemulsification and 25 patients who have undergone SICS. The DALY for phacoemulsification at Day-7 (D-7) is 0.3204, and at Day-21 (D-21), it is 0.3204, while the DALY for SICS at D-7 is 0.3060, and at D-21, it is 0.3158. The incremental cost effectiveness ratio (ICER) for cataract surgery at D-7 is USD $1872.49, and at D-21, it is USD $5861.71, whereas the Indonesian Gross Domestic Product (GDP) is USD $4174.90. In conclusion, the phacoemulsification technique is more cost effective than the SICS technique. The ICER value is very cost effective at D-7 post-surgery compared to at D-21 post-surgery because the ICER is less than 1 GDP per capita per DALY.

    BACKGROUND: To describe the preferred cataract surgery practices among Malaysian ophthalmologists and medical officers in comparison with the recommended practices.

    METHODS: An online questionnaire was sent out in April 2021, to Malaysian Ophthalmologists and medical officers who perform cataract surgeries. The questions were focused on the preferred cataract surgery practices of the participants. All data obtained were collected, tabulated and analysed.

    RESULTS: A total of 173 participants responded to the online questionnaire. 55% of the participants were within 31-40 years of age. 56.1% preferred peristaltic pump over venturi system. 91.3% of participants practised povidone iodine instillation to the conjunctival sac. With regards to the main wound incision, more than half of the surgeons (50.3%) preferred fixed superior incision and 72.3% of them preferred 2.75 mm microkeratome blade. Most of the participants (63%) were inclined towards C-Loop clear intraocular lens (IOL) with a single-handed push preloaded system. 78.6% of the surgeons routinely use carbachol in their cataract surgery.

    CONCLUSIONS: This survey provides some insight into the current practices among Malaysian ophthalmologists. Most of the practices are in line with international guidelines for preventing postoperative endophthalmitis. This article could help trainees and ophthalmologists benchmark and observe the common cataract surgery practices among their seniors and peers in Malaysia.

    It is possible that different techniques used to measure axial length (AL) and anterior chamber depth (ACD) is the cause of discrepancy in refractive outcomes of cataract surgery. This study evaluated the agreement and repeatability of AL and ACD measurements using immersion and contact A-scan biometry techniques and compared the refractive outcomes from both techniques. Twenty four patients were evaluated for agreement and repeatability of AL and ACD measurements using the two different methods. The results were analyzed using Bland and Altman plots. Another 60 patients with age-related cataract were selected to compare the refractive outcomes between both methods. The IOL power was calculated using Sanders- Retzlaff- Kraff- Theoretical (SRK-T) equation. Refraction was determined between four to six weeks postoperatively and the results were analyzed using paired t-test. The results of this study showed good agreement between both techniques was noted with no significant difference detected between measurements (p > 0.05). Significant correlation was found in all parameters (AL: r = 0.99; p < 0.01, r = 0.99; p < 0.01) ACD: r = 0.91; p < 0.01, r = 0.97; p < 0.01). No significant difference in refractive outcomes of post cataract surgery was detected between the two techniques (p = 0.07). This study concludes that contact A-scan biometry and immersion techniques provide reliable results and should not be the cause of discrepancy in the refractive planned and outcome of cataract surgery.

    We describe a potential cause of eye injury, its concerns and ways to prevent it. The first author underwent a left cataract operation and was prescribed eye drops postoperatively. While applying one of the eye drops, he felt an object hitting the lower eyelid. A serrated plastic piece had fallen off the bottle. Had it fallen on the operated site, it might have caused serious untoward complications. Nurses, carers and patients need to be educated to remove the serrated piece from the bottle before applying eye drops. Manufacturers of eye drops should design safer bottles without such serrated pieces to prevent such eye injuries.

    Senile cataract is the most common cause of bilateral blindness and results from the loss of transparency of the lens. Maintenance of the unique tissue architecture of the lens is vital for keeping the lens transparent. Membrane transport mechanisms utilizing several magnesium (Mg)-dependent ATPases, play an important role in maintaining lens homeostasis. Therefore, in Mg-deficiency states, ATPase dysfunctions lead to intracellular depletion of K(+) and accumulation of Na(+) and Ca(2+). High intracellular Ca(2+) causes activation of the enzyme calpain II, which leads to the denaturation of crystallin, the soluble lens protein required for maintaining the transparency of the lens. Mg deficiency also interferes with ATPase functions by causing cellular ATP depletion. Furthermore, Mg deficiency enhances lenticular oxidative stress by increased production of free radicals and depletion of antioxidant defenses. Therefore, Mg supplementation may be of therapeutic value in preventing the onset and progression of cataracts in conditions associated with Mg deficiency.

    INTRODUCTION: Paediatric cataract surgery is challenging with reported post-operative visual acuity (VA) of 0.3LogMar or better varying between 33% to 68% of patients.

    OBJECTIVE: The aim is to document the post-operative refraction, VA and complications of non-traumatic pediatric cataract surgery performed in a tertiary referral center in Malaysia.

    METHODOLOGY: This retrospective study reviewed case notes of all consecutive patients aged 12 years and below who underwent cataract surgery from January 2010 to December 2015. Patients were recruited if they had a minimum of six months post-operative follow-up. Exclusion criteria included traumatic cataract, central nervous system abnormalities, incomplete medical records or pre-existing ocular pathology. Subjects were divided into two groups based on refraction at one month. Subjects with refraction within 1- dioptre of the targeted spherical equivalent were in the success group and the rest were in the failure group.

    RESULTS: A total of 111 subjects were recruited (65 subjects in success group and 46 subjects in the failure group). Mean age at surgery was 33.14 (SD: 33.47) months. The success group had significantly longer axial length (p:0.0045, CI: 0.566-0.994, OR: 0.750). At final review, 44.1%(49/111) subjects had visual acuity of 0.3LogMar or better. The success group had better final mean VA in comparison to the failure group (p:0.034, CI:1.079-7.224, OR: 2.791).

    CONCLUSION: The outcome of non-traumatic paediatric cataract surgery was acceptable with 58.6% achieved targeted refractive correction at 1-month post-operative period. Longer axial length was associated with better refractive outcome. Capsule related complications was the most common intra-operative complication.

    OBJECTIVE: The Ministry of Health introduced the cluster hospital project in Kuala Pilah district in 2016 to allow sharing of resources between the hospitals in the same vicinity. The aim of this study is to compare the demographic profile, prevalence of cataract blindness and low vision among patients who presented for cataract surgery before and after the programme.

    METHODOLOGY: This is a retrospective cohort study of patients who underwent cataract surgery in Kuala Pilah Cluster Hospitals between 2010 and 2017. A total of 2539 records of patients were reviewed. Patients were assigned into two groups: Group 1 (2010-2012)- before the programme (2010-2012) and Group 2 (2015-2017) after the introduction of the programme.

    RESULTS: There was a significant increase in number of cataract cases in the district hospital after the cluster initiative. The mean age of patients undergoing cataract surgery was similar in both groups. The common comorbidities were hypertension (Group 1=57.3%; Group 2=70.8%) and diabetes mellitus (Group 1=40.6%; Group 2=51.1%). In 2010-2012, most of the patients were one eye blind (34.4%), whereas in 2015-2017 majority of patients presented with vision better than 6/18 (43.5%). The proportion of patients with cataract blindness reduced from 6% in 2010-2012 to 4.3% in 2015-2017 (p<0.01).

    CONCLUSION: There is a significant decrease in percentage of patients with cataract blindness and low vision after the introduction of Kuala Pilah Cluster Hospital Program. We believe that that cluster hospital system is effective in improving accessibility to eye care and therefore increases the cataract detection rate.

    The success of cataract surgery is accessed by the improvement in visual acuity and accuracy of the post-operation refractive outcome against the pre-operation refractive target. Hence, the benchmark of 85% of patients achieving a final spherical equivalent within 1D of the desired target is used to monitor the refractive outcome. Meanwhile, the unaided visual acuity threshold of 6/12 after cataract operation is chosen as a yardstick because it allows patients to perform instrumental activities of daily living (IADL) independently without relying on spectacles.

    Background Cataract surgery which is the only scientific method to treat cataracts has evolved from large incisions of intracapsular cataract excision to extracapsular cataract exicison and now modern day phacoemulsification. Anaesthesia too has progressed from general anaesthesia to local and topical anaesthesia. A variety of intraocular lenses are available ranging from rigid to foldable, multifocal and toric. Day care surgeries are becoming the norm these days. Objective Cataract surgery has advanced with new techniques and modalities. We studied the trends of cataract surgery and outcomes over the years. Method We performed secondary data analysis (National Eye Database) of cataract surgery patients in Hospital Melaka (2007 - 2014). Result Most patients were 60-69 years (mean 65.0 years). Primary cataract rose (p<0.05) but there was no difference in laterality and first or second eye (p>0.05). More patients presented with Hypertension and Diabetes (p<0.05). Pterygium encroaching the cornea showed a rise (p<0.05). Phacoemulsification (80.8%) showed a rise while Extracapsular Cataract Extraction (ECCE) (15.4%) declined (p<0.05). More Specialists operated and fewer combined surgeries were performed (p<0.001). Type of anaesthesia did not change (p>0.05). Operative complications reduced (p<0.001). Anterior chamber, scleral fixated and foldable intraocular lenses usage reduced (p<0.05). There was no change in pre-operative visual acuity (p>0.05) but postoperative vision showed a rise in good outcomes (p<0.05). Conclusion Melaka Hospital shows a rise in phacoemulsification and a decline in Extracapsular Cataract Extraction. More patients presented with primary cataracts. More Specialists operated and there was a reduction in intraoperative and postoperative complications. Post-operative visual outcomes showed a remarkable improvement. This improvement is in keeping with the aim of improved vision for all by 2020.

    Background: A randomised single blinded clinical trial comparing the effectiveness of two methods of cataract surgery with intraocular lens implantation: extracapsular cataract extraction (ECCE) and phacoemulsification (PEA) was carried out at Hospital Universiti Kebangsaan Malaysia (HUKM) between March 2000 and August 2001. Methods: The effectiveness of cataract surgery was assessed from the quality of life specifically for vision via Visual Function 14 (VF-14) preoperatively, one week, two months and six months after surgery. Results: The result showed that there was a significant increased in VF-14 scores after a week, two months and six months postoperation compared to the score before surgery for both techniques. However there was no significant difference in VF-14 scores when compared between ECCE and PEA. Conclusions: This study indicated that both techniques give equal benefit to cataract patients. Since effectiveness of cataract surgery with intraocular lens implantation is unrelated to operative procedures, less costly technique should be promoted.

    Introduction: The corneal endothelium is made up of an extremely thin layer of non -regenerating cells essential in keeping the cornea clear. The purpose of this study was to quantify the corneal endothelial cells morphology, visual acuity (VA) and refractive error in patients having femtosecond laser-assisted cataract surgery (FLACS) and conventional phacoemulsification surgery (CPS). Methods: Clinical data from 56 eyes were included in this study. 28 eyes had FLACS surgery and another 28 eyes had CPS. Distance VA, refractive error, corneal thickness and endothelial cells morphology were evaluated pre-operatively and at 1 month follow up. Refractive error was determined subjectively and VA was taken using Snellen chart. Specular microscope was used to measure endothelial cells morphology and central corneal thickness. Mann Whitney test and Spearman correlation analysis were used to analyse the results. Results: There were no statistically significant difference in the mean endothelial cell density (p=0.24), mean central corneal thickness (p=0.68), mean coefficient of variance (p=0.19), mean hexagonality (p=0.44), VA (p=0.72) and postoperative refractive outcome (p=0.66) between both groups. The duration of surgery was noted to have no statistically significant difference between both groups (p=0.08), while the cumulative dissipated energy and torsional time showed a significant difference between groups (p=0.01 and p

    This study was done to correlate the occurrence of posterior capsule rupture among patients with pseudoexfoliation during phacoemulsification. This was a retrospective audit of patients who underwent phacoemulsification type cataract surgery from January 2011 to December 2012 in a tertiary hospital in Malaysia. Data was obtained from the National Eye Database (NED) of Malaysia. The data was analysed using SPSS version 21.0. By using logistic regression analysis, it was found that there was no significant increase in the occurrence of posterior capsule rupture among patients with pseudoexfoliation. Hence, we concluded that there was no correlation between the occurrence of posterior capsule rupture and the presence of pesudoexfoliation among patients who underwent phacoemulsification.

    PURPOSE: To study the prevalence of second eye cataract surgery (SECS), trend in time interval between subsequent surgeries over the years, and factors associated with SECS utilization among patients who underwent cataract surgeries in the Ministry of Health (MOH), Malaysia.

    DESIGN: Secondary cross-sectional analysis of the Malaysian National Eye Database (NED) data.

    METHODS: The Malaysian Cataract Surgery Registry collected data on patients who had cataract surgery from 2002-2004 and 2007-2012. Data collected included demography, operative events, time interval between 2 surgeries, and postoperative visual outcomes. Descriptive analysis was performed.

    RESULTS: Total surgeries increased from 11,954 in 2002 to 30,265 in 2012 with a proportionate increase in SECS (30.7% in 2002 to 34.3% in 2012). Poor vision (<6/12) was reduced from 81.1% to 14.2% after surgery. With improved data capturing, missing data reduced from 29.22% to 1.05%. The time interval between surgeries was 10.58 months in 2002 and 14.49 months in 2012. Malays (40.2%) and those aged 61-70 years (38.1%) had the highest number of SECS. Those aged 40-50 years (10.96 months) and with poorer vision (9.97 months) had the shortest time interval between the 2 surgeries. The commonest surgical method was phacoemulsification (72.3%). Negeri Sembilan State had the highest SECS rate (35.91%) and Melaka had the shortest interval between surgeries (10.15 months).

    CONCLUSIONS: Despite an increase in the number of SECS, the time interval is still long. Poor presenting second eye vision and disparity among different states warrants the health authority's attention and intervention.

    PURPOSE: To investigate the change in the profile of patients who had cataract surgery at Ministry of Health (MOH) hospitals in Malaysia.

    DESIGN: Secondary analysis on Malaysian Cataract Surgery Registry data.

    METHODS: The Malaysian Cataract Surgery Registry, a MOH-initiated registry, collects data on patients who had cataract surgery at the 36 MOH ophthalmology departments including demography, causes of cataract, systemic and ocular comorbidity, preoperative visual acuity (VA), operative details, and postoperative outcomes. This article reviews data on patient profiles from 2002 to 2004 and 2007 to 2011.

    RESULTS: The coverage of cataract surgery was 91.5% (171,482/185,388). Mean patient age was 64.5 years, and 51.6% were women. A high proportion of patients had hypertension (48.9%), diabetes mellitus (37.1%), and diabetic retinopathy (10.7%). Most had senile cataract (93.4%) and one third had second eye surgery. Most patients (82.0%) had preoperative unaided VA of worse than 6/12. Eyes presenting with unaided VA of worse than 3/60 decreased from 62.6% in 2002 to 47.7% in 2011, whereas those with 6/18 to 3/60 increased from 35.2% to 48.5% (P < 0.001). Patients who had extracapsular cataract extraction had worse preoperative VA than those who had phacoemulsification (81.3% vs 40% had vision worse than 3/60).

    CONCLUSIONS: The obvious change in patient profiles was the decreasing number of eyes presenting with worse than 3/60 vision. Compared with developed countries, patients who had cataract surgery at MOH hospitals in Malaysia were younger and had higher associations with diabetes mellitus and diabetic retinopathy.

    PURPOSE: To analyse the visual outcomes of cases with posterior capsule rupture (PCR) compared to those without PCR following phacoemulsification. The occurrence of posterior capsule rupture during phacoemulsification surgery for cataract can have serious implications in the visual recovery. However, recognition of PCR and proper management can yield a successful visual outcome. This study analysed the visual outcomes of cases with PCR compared to those without PCR.

    METHODS: This is a case-control study. All patients who underwent cataract surgery from 2011 to 2012 in Hospital Melaka were traced from the National Eye Database (NED) of Malaysia. The visual outcomes were classified as good, borderline and poor as per WHO guidelines. The data was analysed with SPSS version 12 IBM.

    RESULTS: Out of 80.4% (2519) of eyes that had undergone phacoemulsification (PHACO) type of surgery, 3.06% (77 cases) had posterior capsule rupture complication. There was no significant difference in the visual outcome of borderline between cases with PCR and cases without PCR (Odds Ratio (OR) 0.989; 95% Confidence Interval (CI) 0.382- 2.560). However, cases with PCR were significantly less likely to have good vision compared to those without PCR (OR 0.335; 95% CI 0.157-0.714).

    CONCLUSION: The study reveals that a significant number of patients without PCR had good vision, whereas those with PCR did not get good vision. We would like to suggest meticulous care during phacoemulsification surgery to avoid PCR in order to obtain good visual outcomes.

    A giant retinal tear (GRT) is a full-thickness neurosensory retinal break that extends circumferentially around the retina for three or more clock hours in the presence of a posteriorly detached vitreous. Its incidence in large population-based studies has been estimated as 1.5% of rhegmatogenous retinal detachments, with a significant male preponderance, and bilaterality in 12.8%. Most GRTs are idiopathic, with trauma, hereditary vitreoretinopathies and high myopia each being causative in decreasing frequency. The vast majority of GRTs are currently managed with a pars plana vitrectomy; the use of adjunctive circumferential scleral buckling is debated, but no studies have shown a clear anatomical or visual advantage with its use. Similarly, silicone oil tamponade does not influence long-term outcomes when compared with gas. Primary and final retinal reattachment rates are achieved in 88% and 95% of patients, respectively. Even when the retina remains attached, however, visual recovery may be limited. Furthermore, fellow eyes of patients with a GRT are at higher risk of developing retinal tears and retinal detachment. Prophylactic treatment under these circumstances may be considered but there is no firm evidence of its efficacy at the present time.
