Visual outcome after paediatric cataract surgery: is age a major factor?

Area of Science:

• Ophthalmology
• Pediatric Surgery
• Visual Science

Background:

• Cataract surgery in children presents unique challenges for visual development.
• Optical correction of aphakia is crucial for optimal outcomes post-surgery.

Purpose of the Study:

• To evaluate functional results of unilateral and bilateral cataract surgery in children.
• To compare different aphakic optical correction methods, including intraocular lenses (IOLs), spectacles, and contact lenses.

Main Methods:

• Retrospective analysis of 107 children undergoing cataract surgery between 1985-1995.
• Assessment of visual acuity and binocular vision based on age at surgery and correction method.

Main Results:

• Bilateral cataract surgery in children over 7 months with IOLs resulted in better visual acuity (>20/63) and binocular vision compared to other corrections.
• Pseudophakic eyes showed significantly better visual recovery (90%) than aphakic eyes (46%).
• Early surgery (before 7 months) for unilateral cataracts had a poorer prognosis.

Conclusions:

• Unilateral and bilateral intraocular lens implantation is beneficial for pediatric cataract surgery outcomes.
• Timely intervention before abnormal foveolar function develops is critical for maximizing visual potential.
