AIM: To explore the associations between various characteristics of Malaysian cataract patients and their management, and their post-operative visual outcomes, to inform relevant bodies to reduce cataract-related blindness.
METHODS: We conducted a descriptive secondary data analysis of cataract surgery patients in Melaka Hospital, from 2007 to 2014 using the National Eye Database (NED). Patient-related factors (demographic features, systemic and ocular comorbidities) and management-related factors (surgical duration, type of surgery, type of lens) were analysed for their association with visual outcome (acuity).
RESULTS: Most patients were Malays (48.23%) and Chinese (38.55%) aged 60-79y (range 0-100y). Hypertension (58.61%) and diabetes (44.89%) were major systemic comorbidities. Glaucoma (6.71%) and diabetic retinopathy (10.12%) were the main ocular comorbidities. Other comorbidities were age-related macular degeneration, pterygium, corneal opacities, macula diseases, vitreous haemorrhage, retinal detachment and pseudoexfoliation (0.70%-1.60%). Preoperatively 7150 (55.03%) eyes presented with poor vision. Uncomplicated phacoemulsification performed quickly with foldable lenses gave good results.
CONCLUSION: Primary care physicians should initiate early detection to prevent late presentation of cataracts causing poor vision and should discuss the risks and benefits of cataract surgery while emphasizing the role of pre-existing comorbidities which may affect the visual outcomes. For good results, phacoemulsification should be done within 30min, without complications, using foldable posterior chamber intraocular lens.
