Influence of Biometric Data on Planning Strabismus Surgery

Area of Science:

• Ophthalmology
• Surgical Planning
• Biometry

Background:

• Strabismus surgery requires precise planning for optimal outcomes.
• Optical biometry provides key anatomical data for eye surgery.

Purpose of the Study:

• To assess the impact of optical biometry data (axial eye length, anterior chamber depth) on strabismus surgery planning.
• To evaluate the utility of simulation software incorporating biometry for surgical planning.

Main Methods:

• Retrospective analysis of 92 patients undergoing horizontal strabismus surgery.
• Simulation of strabismus surgery using See++ software, with and without axial eye length data.
• Partial least squares regression and bootstrapping to evaluate the influence of anatomical data on outcomes.

Main Results:

• Surgical simulations showed a slight improvement when axial eye length was included (0.30mm change).
• All patients achieved at least a 25% reduction in strabismus, with 60% achieving ≥75% reduction.
• Anterior chamber depth and axial eye length demonstrated a significant impact on postoperative strabismus extent.

Conclusions:

• Incorporating axial eye length into simulation models aids strabismus surgery planning.
• Anterior chamber depth and axial eye length are crucial factors influencing strabismus surgery outcomes.
