PURPOSE To compare the outcomes of femtosecond laser-assisted cataract surgery (FLACS) with those of conventional phacoemulsification surgery (CPS) for age-related cataracts. METHODS A comprehensive literature search of PubMed, EMBASE, and the Cochrane Controlled Trials Register was conducted to identify randomized controlled trials (RCT) and comparative cohort studies comparing FLACS with CP...

OBJECTIVES To assess the stability of axis and patient satisfaction after toric visian implantable collamer lens (TICL) implantation for moderate to high myopic astigmatism. METHODS Total 33 eyes of 21 consecutive patients who underwent implantation of TICL for the correction of moderate to high myopic astigmatism were recorded and a minimum follow-up of six months was performed. The deviatio...

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 To assess the sensitivity and specificity of predicting refractive error type using information from a four-item questionnaire on the purpose of spectacle use and age at first use. METHODS The Sydney Myopia Study examined 1,740 year 1 (78.9% response) and 2,353 year 7 students (75.3% response) from a random cluster sample of 34 primary and 21 secondary schools across Sydney. Parents o...

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...

Astigmatism is a very common refractive error in infants. The etiology of astigmatism is poorly understood although it may involve pregnant environmental factors. The aim of this study was to examine the association between pregnant nutrition and the risk of infant astigmatism in twins. Total 28 pairs of twins (11 monozygotic and 17 dizygotic), whose mothers had been involved in this study sinc...

Introduction: This small study relates our early experiences with the Limbal Relaxing Incision (LRI) for management of astigmatism in patients undergoing cataract surgery. Aims: To evaluate the efficacy of LRI in the management of primary astigmatism when combined with phacoemulsification. Subjects and methods: Limbal relaxing incisions were performed to correct primary astigmatism in 12 eyes o...
