Objectives. To analyze the corneal astigmatism and axial length values in cataract surgery candidates. Methods. The files of patients who undergone cataract surgery between November 2012 and November 2013 were retrospectively selected and reviewed. The preoperative corneal keratometry measurements in the flat and steep axis and the axial lengths of the patients were recorded. Results. The study...

PURPOSE To study the lenticular problems in children presenting at an apex institute. METHODS Retrospective analysis of records (< 14 years) of new lens clinic cases was done. RESULTS Of 1,047 children, 687 were males. Mean age at presentation was 6.35 ± 4.13 years. Developmental cataract was seen in 45.6% and posttraumatic cataract in 29.7% of patients. Other abnormalities were cataract wi...

OBJECTIVE To compare the corneal astigmatism before and after the excision of pterygium and also to determine the correlation of pterygium size with the postoperative corneal astigmatism. STUDY DESIGN Cross-sectional interventional study. PLACE AND DURATION OF STUDY Eye Department, Combined Military Hospital, Abbottabad, from May 2011 to March 2012. METHODOLOGY Thirty patients underwent p...

Noncycloplegic refractions of 1,000 children aged 0-6 years revealed a high incidence of astigmatism, especially in the first 2 years of life. Before age 41/2 years, most of the astigmatism was against-the-rule and after that age most was with-the-rule. Of 19 children who did not show astigmatism in the first year, only one acquired it by 4 years. Of 29 children who had large amounts of astigma...

PURPOSE The primary objective of the study was to explore the statistics of ocular higher-order aberrations in a population of primary and secondary school children. METHODS A sample of 557 children aged 10-15 years were selected from two primary and two secondary schools in Heraklion, Greece. Children were classified by age in three subgroups: group I (10.7±0.5 years), group II (12.4±0.5 yea...

BACKGROUND A chalazion is a common eyelid disease that causes eye morbidity due to inflammation and cosmetic disfigurement. Corneal topographic changes are important factors in corneal refractive surgery, intraocular lens power calculations for cataract surgery, and visual acuity assessments. However, the effects of chalazia on corneal astigmatism have not been thoroughly investigated. The chan...

THE EXCENTRIC ASTIGMATISM PRK, A PHOTOREFRACTIVE METHOD TO CORRECT CORNEAL ASTIGMATISM USING TEE 193-NM EXCIMERLASER HUETZ,W.W., EOFFMANN,P.C., ECKHARDTJ3.B. Pumore: The Excentric Astigmatism PRK is a method to correct comeal astigmatism with two peripheral ablations which are performed outside an untreated central zone. Method% Two peripheral ablations of 3.4 mm diameter are performed outside ...

PURPOSE To evaluate the effect of phacoemulsification through clear cornea incision in the steepest meridian (ISM), on the magnitude of preoperative keratometric astigmatism. To map the magnitude of surgically induced astigmatism (SIA) by clear cornea incision in the positions: nasal (N), temporal (T), superior temporal (ST) and inferior temporal (IT). METHODS A prospective keratometric study...
