Contribution of posterior corneal astigmatism to total corneal astigmatism.
PURPOSE To determine the contribution of posterior corneal astigmatism to total corneal astigmatism and the error in estimating total corneal astigmatism from anterior corneal measurements only using a dual-Scheimpflug analyzer. SETTING Cullen Eye Institute, Baylor College of Medicine, Houston, Texas, USA. DESIGN Case series. METHODS Total corneal astigmatism was calculated using ray trac...
متن کاملcorneal regrafts for correction of post-keratoplasty anisometropia and high astigmatism in two patients with keratoconus
purpose: to report two patients with keratoconus who underwent regrafting to correct anisometropia and high astigmatism after penetrating keratoplasty. patients and findings: the first case is a 34-year-old man with keratoconus who had undergone penetrating keratoplasty. the sutures were removed 6 months postoperatively that led to high hyperopia. regraft was performed considering vitreous leng...
متن کاملهمبستگی آستیگماتیسم رفرکتیو، قرنیه‌ای و لنتیکولار در افراد داوطلب جراحی رفرکتیو
Background and purpose: Astigmatism is a common optical dysfunction, effective on various visual outcomes and one of the important criteria of refractive surgery. The aim of present study was to evaluate the correlation between refractive, corneal and residual astigmatism in refractive surgery candidates. Materials and methods: In this cross-sectional descriptive, analytical study, 200 patient...
متن کاملSurgical management of astigmatism with toric intraocular lenses.
Correction of corneal astigmatism is a key element of cataract surgery, since post-surgical residual astigmatism can compromise the patient's uncorrected visual acuity. Toric intraocular lenses (IOLs) compensate for corneal astigmatism at the time of surgery, correcting ocular astigmatism. They are a predictable treatment. However, accurate measurement of corneal astigmatism is mandatory for ch...
متن کاملCorneal topographic astigmatism (CorT) to quantify total corneal astigmatism.
PURPOSE To evaluate the performance of corneal topographic astigmatism (CorT) based on total corneal power measurements. METHODS Anterior, posterior, and total corneal power measurements of 526 virgin eyes obtained using the CSO Sirius tomographer (Costuzione Strumenti Oftalmici, Scandicci, Florence, Italy) were analyzed. Individual CorTs were created from each set of data. These CorTs were a...
