Comparative study of post-operative astigmatism following phacoemulsification with sutured versus un-sutured wound.
Pak J Med Health Sci Jan ;5(2):243-7.

Purpose: To compare frequency of post-operative astigmatism in patients undergoing sutured and unsutured anterior limbal incision in phacoemulsification Material and method: 120 patients for study were admitted from outpatient department. An informed consent was obtained and patients were divided in two groups A & B by random sampling. Phacoemulsifcation was done, with one stitch applied in group A while no stitch in group B. Removal of stitch was done at 3rd post operative week. Follow up visits was done at 6th post operative week. K readings were taken with keratometer and were recorded on a proforma. Results: Surgically induced astigmatism (SIA) in group A was 73.3% and in group B was 11.7% in total of 120 patients with 60 patients in each group. The p value was less than 0.005 and by conventional criteria; this difference is considered to be statistically significant. . Conclusion: Surgically induced astigmatism is more common in phacoemulcification when suture is applied for wound closure.
