Abstract
Purpose
To evaluate the efficacy of cyclosporine 0.05% in reduced tear production sign and dry eye symptoms after cata-ract surgery.
Methods
This hospital-based prospective randomized trial included 43 patients of 83 eyes who underwent phacoemulsification. Tear break-up time, Schirmer’s test, corneal and conjunctival stain, and ocular surface disease index were performed for all pa-tients at preoperative 1 day, and 1 day, 1 week, 1 month, and 2 months postoperatively. Group 1 received carboxymethylcellulose 0.5%, group 2 received twice-daily cyclosporine 0.05%, and group 3 did not receive any additional eye drops.

![]() | Figure 2.Schirmer test I at pre-op and post-op 1 day, 1 week, 1 month, and 2 months. Schirmer test I of group 2 increased statistically significant between post-op 1 month and 2 months (Group 1 = Carboxymethylcellulose 0.5%, Group 2 = Cyclosporine 0.05%, Group 3 = No additional eye drops). |
![]() | Figure 3.Corneal and conjunctival staining at pre-op and post-op 1 month, 2 months. Group 2 had lowered corneal and conjunctival staining grades 2 months after cataract surgery (Group 1 = Carboxymethylcellulose 0.5%, Group 2 = Cyclos- porine 0.05%, Group 3 = No additional eye drops). |
![]() | Figure 4.Mean ocular surface disease index (OSDI) score at pre-op and after surgery. The OSDI score decreased more in group1 and 2 than group 3 from 1 week after surgery to 2 month (Group 1 = Carboxymethylcellulose 0.5%, Group 2 = Cyclosporine 0.05%, Group 3 = No additional eye drops). |
