Visual complaints and binocular function in bilaterally aphakic persons with cataract glasses.

Area of Science:

• Ophthalmology
• Vision Science

Background:

• Senile cataracts significantly impair vision.
• Cataract spectacles are crucial for visual rehabilitation post-surgery.

Purpose of the Study:

• To evaluate visual complaints and binocular function in patients after cataract spectacle fitting.
• To assess the impact of pre-operative monocular visual function duration on outcomes.

Main Methods:

• Seventy-one patients were examined and questioned 18 months post-spectacle fitting.
• Assessed distance and near visual function, presence of exotropia, and diplopia.
• Investigated sensory binocular function using Titmus' sterotest.

Main Results:

• No distance vision complaints were reported; most patients managed daily activities independently.
• 16 patients developed exotropia, with only two experiencing diplopia, which resolved after spectacle decentration.
• 35 patients achieved 40 inches/arc on the sterotest, indicating some level of stereopsis.
• Duration of monocular visual function did not influence postoperative motor or sensory binocular function.

Conclusions:

• Cataract spectacles effectively address distance vision issues post-surgery.
• While some patients develop exotropia, significant diplopia is uncommon and often manageable.
• Postoperative binocular function is generally adequate, with duration of pre-operative monocularity not being a determining factor.
