Microincision Versus Smallincision Combined Surgery

N/AUnknownNCT01198483

The Ludwig Boltzmann Institute of Retinology and Biomicroscopic Laser Surgery80 enrolled

Overview

The purpose of this study is to compare refractive outcomes after two different types of combined cataract surgery, namely microinscision cataract surgery and smallincision cataract surgery, and sutureless 23-gauge vitrectomy in patients presenting with vitreoretinal disorders and coexisting cataracts.

Purpose: To compare refractive outcomes after combined cataract and vitreoretinal surgery. Methods: Patients with a diagnosis of vitreoretinal disorder and a coexisting significant cataract were randomly assigned to be treated with a microincision cataract surgery and a 23-gauge vitrectomy (treatment group 1) or with a smallincision cataract surgery and a 23-gauge vitrectomy (treatment group 2). Main outcome measures: Refractive outcomes, stability of the intraocular lens (IOL), intraocular pressure (IOP) and functional outcomes.

Outcomes

Primary Outcomes

Refractive outcome

Refractive outcome includes autorefraction using Humphrey Automatic Refractor/Keratometer(Carl Zeiss AG, Oberkochen, Germany) and subjective manifest refraction.

Time frame: 12 weeks after surgery

Secondary Outcomes

measurements of anterior chamber depth (ACD)

measurements of anterior chamber depth (ACD )to evalute the stability of the intraocular lens (IOL) using the Pentacam (OCULUS GmbH, Wetzlar, Germany)

Time frame: 12 weeks after surgery

intraocular pressure (IOP)

to evaluate the stability of the eye after sutureless 23-gauge vitrectomy

Time frame: 12 weeks after surgery

functional outcome

Functional outcome includes testing of best corrected distance and near visual acuity (Logarithm of the minimum angle of resolution (logMAR) charts and Radner Reading charts)and optical coherence tomography (OCT)

Time frame: 12 weeks after surgery
