RESUMEN

Purpose: A prospective cohort study was conducted in a tertiary eye care centre to study the incidence of tear film dysfunction and its recovery in diabetics and non-diabetics after clear corneal phacoemulsification. Methods: A total of 50 diabetics and 50 non-diabetics underwent clear corneal phacoemuslfication. Schirmer’s I test (SIT), tear film break-up time (TBUT), corneal staining, tear meniscus height (TMH), and ocular surface disease index (OSDI) assessment were done preoperatively, postoperatively at 7 days, 1 month, and 3 months in both groups to assess tear film function. Results: Both groups showed decreased SIT and TBUT values on postoperative Day 7, after which they gradually improved. SIT and TBUT values in diabetics were significantly lower than that in non-diabetics postoperatively (P < 0.001). SIT in non- diabetics reached baseline levels at postoperative 3 months. OSDI scores reached peak levels in both groups on postoperative Day 7, but were higher in diabetics than non-diabetics (P < 0.001). OSDI scores gradually improved over 3 months but remained over baseline levels in both groups. Corneal staining was positive in 22% diabetics and 8% non-diabetics at postoperative Day 7. However, none of the patients had corneal staining at 3 months. Tear meniscus height (TMH) did not reveal any significant difference between the two groups at any time interval. Conclusion: We concluded that tear film dysfunction after clear corneal incision occurs in both groups, but is more severe and recovers more slowly in diabetics than non-diabetics.

RESUMEN

Purpose: To estimate the postoperative astigmatism after small?incision cataract surgery (SICS) done by junior residents at the end of 1 and 3 months. Methods: This observational longitudinal study was conducted at the Department of Ophthalmology of a tertiary eye care hospital and research center. 50 patients enrolled in the study underwent manual small incision cataract surgery by junior residents. Preoperative detailed ocular examination was done, which included keratometric estimation using autokeratometer (GR?3300K). Incision length, distance of incision from the limbus, and type of suturing technique were noted. Postoperatively, keratometric readings were noted at 1 and 3 months. Astigmatism (surgically induced astigmatism [SIA]) was estimated using Hill’s SIA calculator version 2.0. All the analyses were performed using Statistical Package for the Social Sciences (SPSS) ver. 26.0 (IBM Corp., USA) software, and the statistical significance was tested at a 5% level. Results: Out of 50 patients, 54% had SIA between 1.5 and 2.5 D and 32% had SIA of more than 2.5 D. Only 14% had SIA less than 1.5 D at the end of 1 month. While 52% had SIA between 1.5 and 2.5 D, 22% had SIA between 1.5 and 2.5 D and 26% had SIA less than 1.5 D at the end of 3 months. Conclusion: The SIA in most of the SICS done by junior residents was above 1.5 D. It depended mainly on the incision length, its distance from the limbus, and the suturing technique.
