About

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.

Full description

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.

Enrollment: 80 estimated patients

Sex: All

Ages: 60+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• diagnosis vitreoretinal disorder with coexisting cataract
• combined surgery
• age over 60 years
• IOL master for preoperative intraocularlens (IOL) calculation

Exclusion criteria

• ultrasound for IOL calculation due to hazy media (dense cataract,vitreous hemorrhage)
• macular edema, proliferative diabetic retinopathy
• myopia or hyperopia more than 5 diopters, astigmatism more than 2 diopters
• previous refractive surgery, retinal detachment surgery, glaucoma surgery and vitrectomy
