Comparative Evaluation of Postoperative Dry Eye Changes Following Phacoemulsification and Small Incision Cataract Surgery
Priyanka Patra, Sikta RoyAbstract
Purpose:
The purpose of the study was to evaluate and compare postoperative changes in tear film function and ocular surface parameters following phacoemulsification and small incision cataract surgery (SICS).
Methods:
This prospective comparative study included 200 eyes of 200 patients undergoing cataract surgery, of which 90 eyes underwent phacoemulsification and 110 eyes underwent SICS. Tear film assessment was performed preoperatively and at 1 week and 1 month postoperatively using the Schirmer test I, tear breakup time (TBUT), and the Ocular Surface Disease Index (OSDI). Patients with preexisting dry eye disease or systemic conditions affecting tear production were excluded. Statistical analysis was performed using paired and unpaired Student’s
Results:
Both groups demonstrated a significant reduction in Schirmer test and TBUT values at 1 week postoperatively, with partial recovery at 1 month. The decline was significantly greater in the SICS group. OSDI scores increased postoperatively in both groups but were consistently higher following SICS.
Conclusion:
Cataract surgery induces transient postoperative dry eye changes. However, phacoemulsification is associated with milder ocular surface disturbance and faster recovery compared with SICS.
