Polar Value Analysis of Low to Moderate Astigmatism with Wavefront-Guided Sub-Bowman Keratomileusis

open access: yesJournal of Ophthalmology, 2017
Purpose. To evaluate the astigmatic outcomes of wavefront-guided sub-Bowman keratomileusis (WFG-SBK) for low to moderate myopic astigmatism. Methods. This study enrolled 100 right eyes from 100 patients who underwent WFG-SBK for the correction of myopia ...

Corneal transplantation: Restoring sight to the blind

open access: yesActa Ophthalmologica, EarlyView.
Abstract Corneal blindness is one of the leading causes of vision loss worldwide. Transplantation of the cornea can restore vision and make blind patients see again. Corneal transplant surgery has undergone major evolution in recent decades with the advent of minimally invasive lamellar surgical approaches such as DMEK and DALK.

Childhood ocular safety after postnatal exposure to topical dexamethasone during retinopathy of prematurity screening

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Dexamethasone eye drops are being introduced off‐label to prevent progression of severe retinopathy of prematurity (ROP). We evaluated ophthalmologic outcomes in early childhood after postnatal topical dexamethasone exposure in pre‐term infants at a standardized follow‐up examination.

Improving the Toric Intraocular Lens Calculation by Considering Posterior Corneal Astigmatism and Surgically-induced Corneal Astigmatism [PDF]

open access: yesKorean Journal of Ophthalmology, 2018
To investigate the effect of surgically induced corneal astigmatism (SICA) and total corneal astigmatism (TCA) estimation on the anterior corneal astigmatism (ACA)-based toric intraocular lens (IOL) calculation.Data from preoperative and postoperative corneal astigmatism, postoperative visual acuities, and refractive outcomes were collected.
