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.
