Femtosecond Laser-assisted Arcuate Incisions Versus Manual Arcuate Incisions Outcomes

2019-10-21 12:45:43 | BioPortfolio


This study is designed to compare the effectiveness of LenSx laser arcuate relaxing incisions vs. manual (blade) arcuate relaxing incisions in patients with low, but significant, levels of astigmatism.


This study is a comparative, prospective, randomized contralateral eye study of visual outcomes after LenSx laser arcuate relaxing incisions utilizing the Woodcock nomogram at 90% thickness vs. manual (blade) fixed keratome diamond knife at 600 microns for arcuate relaxing incisions utilizing the Donnenfeld nomogram. Subjects will be assessed pre-operatively and at 1 day, 1 month and 3 months post-operatively. Clinical evaluations will include measurement of visual acuity, manifest refraction and corneal astigmatism measurement with the Lenstar and slit lamp exam.

Comparison of Femto-laser and Manually Created Clear Corneal Incisions During Cataract Surgery

The aim of this study is to test the hypothesis, that in terms of Surgically Induced corneal Astigmatism (SIA), Higher-order Aberrations (HOA), and wound geometry the femtosecond clear cor...

Release of Proinflammatory Cytokines (IL-1β, IL-6) and Total-prostaglandin (PG) Following Femtosecond Laser-assisted Cataract Surgery Compared to Manual Cataract Surgery

Wound Architecture and Functional Outcome After Cataract Surgery With Manual vs.Femtosecond Laser Assisted Procedures

This study is the long term analysis of two types of FSL 3-plane corneal wound profiles, namely CT1 and CT2 obtained after a FSL cataract surgery.

Topical 0.1% Bromfenac Sodium and Prostaglandin E2 Inhibition in Cataract Surgery

Since a new generation of femtosecond lasers became available for cataract surgery in 2009, the use of this image-guided system has provided several benefits, including a reduction in phac...

Clinical Research of Femtosecond Laser-Assisted Cataract Surgery

Since femtosecond laser was approved for cataract surgery by FDA in 2010, femtosecond laser assisted cataract surgery (FLACS) has demonstrated high precision of capsulotomy, reduced phacoe...

Cataract surgery in corneal transplantation.

Corneal diseases are often associated with lens opacity. The present article reviews the recent advances in the management of cataract and corneal transplant.

Stromal keratophakia.

Stromal keratophakia was first performed by José Ignacio Barraquer in the 1960s. The refractive lamellar keratoplasty technique was intensely pursued in the 1980s as a method to alter corneal refract...

Medical and Biotech [MESH] Definitions

A surgical procedure to correct MYOPIA by CORNEAL STROMA subtraction. It involves the use of a microkeratome to make a lamellar dissection of the CORNEA creating a flap with intact CORNEAL EPITHELIUM. After the flap is lifted, the underlying midstroma is reshaped with an EXCIMER LASER and the flap is returned to its original position.

Loss of CORNEAL ENDOTHELIUM usually following intraocular surgery (e.g., cataract surgery) or due to FUCHS' ENDOTHELIAL DYSTROPHY; ANGLE-CLOSURE GLAUCOMA; IRITIS; or aging.

A technique utilizing a laser coupled to a catheter which is used in the dilatation of occluded blood vessels. This includes laser thermal angioplasty where the laser energy heats up a metal tip, and direct laser angioplasty where the laser energy directly ablates the occlusion. One form of the latter approach uses an EXCIMER LASER which creates microscopically precise cuts without thermal injury. When laser angioplasty is performed in combination with balloon angioplasty it is called laser-assisted balloon angioplasty (ANGIOPLASTY, BALLOON, LASER-ASSISTED).

A surgical technique to correct REFRACTIVE ERRORS of the EYE, such as MYOPIA and ASTIGMATISM. In this method, a flap of CORNEAL EPITHELIUM is created by exposure of the area to dilute alcohol. The flap is lifted and then replaced after laser ablation of the subepithelial CORNEA.

New blood vessels originating from the corneal veins and extending from the limbus into the adjacent CORNEAL STROMA. Neovascularization in the superficial and/or deep corneal stroma is a sequel to numerous inflammatory diseases of the ocular anterior segment, such as TRACHOMA, viral interstitial KERATITIS, microbial KERATOCONJUNCTIVITIS, and the immune response elicited by CORNEAL TRANSPLANTATION.
