AIM: To study the incidence of dry eye and its determinants in patients undergoing cataract surgery.
MATERIAL AND METHODS: 120 patients with senile cataracts underwent Schirmer’s test, Tear break up Time (TBUT) test, Lissamine green staining of cornea and conjunctiva, and Ocular Surface Disease Index (OSDI) were carried out for evaluation of dry eye preoperatively and further on 1st and 2nd follow up at 1 week and 1 month after cataract surgery.
RESULTS: Mean age of patients was 59.25+9.77 years majority of which were males (n=73; 60.83%). None of the patients had dry eye at the time of enrollment as per the criteria of our study. Postoperatively Schirmer’s test values ranged between 12-35 and 8-24 on 1st and 2nd follow up respectively. Mean TBUT was 13.16 ± 2.45 and 9.64 ± 2.20 seconds, while Lissamine green staining score was 3 in 67 (55.8%) and 1 in 67 (55.8%) subjects on 1st and 2nd follow up respectively. OSDI values ranged from 1-30 and 10-33 with a mean of 25.97 ± 5.34 and 11.96 ± 7.47 respectively on the successive follow-ups. On the first follow up, 89.1% of the patients undergoing phacoemulsification were found to have grade 2 dry eye (p<0.001), while 92.2% of the patients undergoing SICS grade 2 dry eye(p<0.001). On the second follow up, among the patients who underwent phacoemulsification 92.2% had grade 0 and 82.1% of the patients who underwent SICS 82.1% had grade 0 dry eye.(p<0.001)
CONCLUSION: The incidence of dry eye after cataract surgery, irrespective of the demographic and anthropometric profile, type of surgical procedure, time of microscopic exposure and amount of energy used was quite high and was almost independent of these variables. This dryness was transient in nature and showed a declining trend, tending to achieve normalization by the end of one month.
