Objective Changes in the Contralateral Eye after Unilateral Cataract Surgery.

Area of Science:

• Ophthalmology
• Ophthalmic Surgery

Background:

• Cataract surgery is a common procedure.
• The effects on the contralateral (fellow) eye are not fully understood.

Purpose of the Study:

• To evaluate objective changes in the fellow eye after unilateral cataract surgery.
• To assess the impact of monocular cataract surgery on contralateral ocular parameters.

Main Methods:

• Retrospective observational study of 44 patients.
• Collected data included visual acuity, intraocular pressure, contrast sensitivity, and anterior segment OCT parameters.
• Measurements were taken preoperatively and at 1 week and 1 month postoperatively.

Main Results:

• Fellow eye pupil size decreased significantly post-surgery.
• Anterior chamber depth in the fellow eye increased significantly.
• Uncorrected distance visual acuity (UDVA) of the fellow eye improved significantly.

Conclusions:

• Unilateral cataract surgery leads to positive changes in fellow eye anatomy and visual function.
• These contralateral effects are important considerations for surgical planning in cases requiring monocular surgery.
