Crossed versus conventional pseudophakic monovision: Patient satisfaction, visual function, and spectacle...

Area of Science:

• Ophthalmology
• Refractive Surgery

Background:

• Pseudophakic monovision is a refractive strategy after cataract surgery.
• Crossed monovision involves correcting one eye for distance and the other for near, but with the non-dominant eye corrected for distance and the dominant eye for near.
• Conventional monovision follows the standard approach.

Purpose of the Study:

• To compare patient satisfaction, visual function, and spectacle independence between crossed and conventional pseudophakic monovision.
• To evaluate the efficacy of crossed monovision in mild anisometropia.

Main Methods:

• Retrospective comparative cohort study analyzing cataract surgery records from 1999-2013.
• Identified and matched patients with crossed and conventional monovision based on multiple parameters.
• Administered surveys to assess patient satisfaction and spectacle independence.

Main Results:

• No significant differences in eye-hand/foot coordination or depth perception between groups.
• Slightly higher patient satisfaction in the crossed monovision group (P = .028).
• Improved nighttime driving ease (P = .025) and intermediate spectacle independence (77% vs. 50%, P = .037) in the crossed monovision group.

Conclusions:

• Crossed pseudophakic monovision is a viable alternative to conventional monovision.
• Both methods provide similar outcomes in patients with mild anisometropia.
• Crossed monovision may offer specific advantages in certain visual tasks.
