Torsional and flattening effect on corneal astigmatism after cataract surgery: a retrospective analysis
BACKGROUND To evaluate the torsional and flattening effect of steep meridian incisions and influence of posterior corneal astigmatism (PCA) on total corneal astigmatism (TCA) after cataract surgery. METHODS One hundred thirty-two eyes underwent cataract surgery with steep meridian 2.2 mm microcoaxial and 2.85 mm conventional clear corneal incisions. Eyes were divided into with-the-rule (WTR) ...
متن کاملInfluence of posterior corneal astigmatism on postoperative refractive astigmatism in pseudophakic eyes after cataract surgery
BACKGROUND To examine the influence of posterior corneal astigmatism on postoperative refractive astigmatism in pseudophakic eyes after cataract surgery. METHODS The study enrolled 64 pseudophakic eyes of 50 patients (71.8 ± 9.9 years old, mean ± standard deviation) who had undergone phacoemulsification with non-toric IOL implantation. Refractive astigmatism was measured using an auto ref-ker...
متن کاملCorneal astigmatism after micro-incision cataract operation.
GOALS To evaluate the effect of micro-incision (2.2 mm) and small-incision (3.0 mm) coaxial phaco-emulsification on surgically induced astigmatism (SIA). METHODS Cataract patients (n = 60, 60 eyes) were randomized into two groups: 30 eyes in the 2.2-mm incision group, 30 eyes in the 3,0-mm group. Phaco-emulsification was followed by intraocular lens implantation via the Monarch II injector wi...
متن کاملEffect of unilateral congenital cataract surgery on ocular axial length growth and corneal flattening.
OBJECTIVE The aim of this article is to study the effect of unilateral congenital cataract surgery on ocular growth and corneal flattening. METHODS This is a cross-sectional study of 59 patients operated on due to a unilateral congenital cataract. The median age of the patients at the time of diagnosis was 17 months (interquartile range, 5-39 months). The median age at cataract the time of su...
متن کاملCorneal astigmatism in leprosy and its importance for cataract surgery
Background: In leprosy, the eyes are frequently affected and many patients were found to have a higher degree of corneal astigmatism than expected during their routine cataract work up. Aim: To compare pre-existing (before any surgical intervention) corneal astigmatism in leprosy patients as compared to age-matched normal controls. Methods: A retrospective study was done, using the charts of le...
