Abstract Details

Purpose:

1. To study tear film changes after phacoemulsification cataract surgery and to investigate effect of location of clear corneal incision site on tear film tests after surgery . 2.To highlight possible pathogenic factors that play role in occurrence or aggravation of dye eye changes after phacoemulsification surgery.

Setting:

The study was conducted in department of Ophthalmology, Dr.Baba Saheb Ambedkar Medical College and Hospital, Rohini, New Delhi.

Methods:

We enrolled 50 eyes of 50 patients with senile cataract requiring phacoemulsification in a prospective randomized study. Surgery was performed with Superior clear corneal Incision in 25 patients and with temporal clear corneal Incision in another 25 patients . All patients were studied using ocular surface disease index (OSDI) score 3 days before cataract surgery and 7 days, 1 month and 3 month Post operatively. Tear break-up time (TBUT), Schirmer-1 (ST-1) and Conjunctival impression cytology to study mean goblet cell density from the corresponding conjunctival region and lower lid covered region were carried out at the same time.

Results:

All the tear film tests studied on the eyes showed deterioration following phacoemulsification surgery . The ST 1 , TBUT and Impression cytology mean goblet cell density results differed significantly in pre and post operative examination in both the incision location groups (p<0.0005) .The results of these tests were not statistically different according to incision location. OSDI indicated that most patients developed dry eye symptom after surgery ,however there was no statistically significant difference in OSDI score according to incision location. Mean goblet cell density showed statistically significant deterioration in inferior region as compared to superior and temporal region (p<0.0005).

Conclusions:

Phacoemulsification cataract surgery can cause or aggravate dry eye symptom and affect the tear film tests values in the post operative period upto 3 months . Eye drops should be carefully administered before and after cataract surgery to avoid or reduce the occurrence of dry eye changes postoperatively. The location of the clear corneal incision had no effect on the tear film tests.
