AIM: To study the prevalence of complications of cataract surgery and any association between the occurrence of complications and experience of surgeon, type of surgery, type of anaesthesia and visual outcome.
METHODS: This was a retrospective study of patients who underwent cataract surgery over a period of two years in a district hospital in Malaysia. The demographic details of patients, type of surgery done, as well as type of anaesthesia used and experience of the surgeon were noted. The types of intraoperative and postoperative complications were recorded. The final best corrected visual outcome was recorded.
RESULTS: Complications occurred in 11.1% of the total 1007 patients operated. Posterior capsule rupture (3.6%) was the most common complication. The experience of the surgeon and the type of anaesthesia used did not affect complications during surgery. Intracapsular cataract extraction (ICCE) and phacoemulsification converted to extracapsular cataract extraction (ECCE) were significantly associated with more complications (P<0.001). The visual outcome was significantly poor in patients with complications (P<0.001).
CONCLUSION: The occurrence of complications during cataract surgery significantly affected the visual outcome. The type of surgery done was associated by the occurrence of complications. However, the experience of the surgeon and the type of anaesthesia used did not affect the occurrence of complications. We recommend that particular attention be given to ICCE and phacoemulsification converted to ECCE to minimise the complications and thereby reducing the chances of poor vision postoperatively.
