Effect of opposite Clear Corneal Incision (CCI) on Corneal Higher -Order Aberrations after Phacoemulsification

Abstract

Nowadays, care of a cataractous patient greatly exceeds surgical removal of the opacified lens. In a step foreword to welfare of the elderly, phacoemulsification can perform as a refractive tool, addressing both spherical and astigmatic refractive errors. The aim of that work was to evaluate safety and effectiveness of OCCIs, as an innovative procedure for correction of corneal astigmatism, during phacoemulsification. Newer generations of IOLs have been introduced, aiming at obtaining the best visual function possible. It is more logic to address the first order aberrations, like astigmatism, ahead of addressing second order aberrations, like asphericity. Several methods have been introduced for correction of astigmatism. Limbal relaxing incisions and toric IOLs are considered as main procedures for correction of astigmatism. However, OCCIs are simple and easy technique, which requires no extra fees or skills. The study assessed 64 patients, who underwent phacoemulsification. Preoperative and postoperative corneal topography was done, documented and statistically analyzed for each patient.
