Strabismus patterns after cataract surgery in adults.

Area of Science:

• Ophthalmology
• Neuroscience

Background:

• New-onset binocular diplopia is a rare complication following cataract surgery.
• Understanding its causes and risk factors is crucial for patient management.

Purpose of the Study:

• To analyze the causes, risk factors, and treatment outcomes of new-onset binocular diplopia after cataract surgery.
• To identify specific ocular alignment and motility patterns associated with this complication.

Main Methods:

• Retrospective study of 40 consecutive adult patients experiencing new-onset diplopia post-cataract surgery.
• Evaluation of risk factors including anesthesia type and preoperative strabismus.
• Analysis of ocular alignment and motility patterns.

Main Results:

• Regional anesthesia was identified as the primary risk factor (37/40 patients).
• Vertical strabismus was prevalent (37/40 patients), with distinct patterns after left (Type 1a) and right (Type 2) eye surgery.
• 17 patients required strabismus surgery.

Conclusions:

• Regional anesthesia is a significant risk factor for postoperative diplopia after cataract surgery.
• Specific patterns of vertical strabismus are associated with surgery on either the left or right eye.
• Further investigation into strabismus patterns and management is warranted.
