Study of Central Corneal Thickness (CCT) bBefore and aAfter Small-Incision Cataract Surgery (SICS) and phacoemulsification surgery

Shrikant Deshpande, Aarti Agarwal, Prachi Shah, Yash Gala

Abstract


Purpose: To highlight the importance of measurement of central corneal thickness (CCT) which is an indirect indicator of corneal endothelial dysfunction after cataract surgery.

Materials and Methods: This was a randomised control trial involving 101 patients who presented with cataract. Cataracts were graded using Lens Opacities Classification system grading. Fifty-one patients underwent small incision cataract surgery (SICS) and 50 underwent phacoemulsification (PHACO). Patients with any other ocular pathology were excluded.

Results: There was significant improvement in the best corrected visual acuity (BCVA) comparable in both groups. There was a statistically  significant increase in central corneal thickness on day 7th and 30th post op. The change in the CCT and BCVA was comparable between SICS and PHACO on day 30th post op.

Conclusion: The increase in CCT suggests that there was some endothelial cell loss leading to change in corneal thickness but not to the extent of causing visual impairment. SICS and phacoemulsification surgery are  comparable in respect to visual rehabilitation. Manual SICS is still a safe and cost-effective option in the developing world. Proper case selection, diligent surgery, and adequate postoperative care are essential to maintain a clear cornea.
