Visual outcomes after cataract surgery in monocular compared to binocular patients: a case-control study

Area of Science:

• Ophthalmology
• Clinical Research
• Surgical Outcomes

Background:

• Monocular vision loss presents unique challenges for cataract surgery planning.
• Understanding ocular comorbidities in monocular patients is crucial for managing expectations and outcomes.

Purpose of the Study:

• To identify ocular comorbidities and causes of blindness in monocular patients.
• To compare cataract surgery outcomes between monocular and binocular patients.

Main Methods:

• A single-center case-control study compared 80 monocular patients with 80 binocular patients undergoing cataract surgery.
• Data collected included demographics, medical history, and surgical details.
• Statistical analysis used Student's t tests and Fisher's exact tests.

Main Results:

• Monocular patients were older and had higher rates of ocular comorbidities (40% vs. 23%).
• Amblyopia, age-related macular degeneration, glaucoma, and diabetic retinopathy were common in monocular patients.
• Visual acuity was lower in monocular patients pre- and post-surgery, but visual improvement and complication rates were similar between groups.

Conclusions:

• Cataract surgery in monocular patients is as safe as in binocular patients.
• Monocular patients experience significantly delayed cataract surgery compared to binocular patients.
