Hyperopic corneal refractive surgery in patients with accommodative esotropia and amblyopia

Area of Science:

• Ophthalmology
• Refractive Surgery
• Pediatric Ophthalmology

Background:

• Accommodative esotropia and amblyopia are common pediatric eye conditions.
• Hyperopic refractive errors can contribute to accommodative esotropia.
• Current treatments focus on managing refractive error and improving visual acuity.

Purpose of the Study:

• To investigate the impact of hyperopic excimer corneal refractive surgery on ocular alignment and stereopsis.
• To evaluate changes in visual acuity and refractive error post-surgery in patients with accommodative esotropia and amblyopia.

Main Methods:

• A prospective study involving 13 patients (26 eyes) with accommodative esotropia and amblyopia.
• Patients underwent bilateral hyperopic corneal refractive surgery (LASIK or LASEK).
• Pre- and postoperative assessments included visual acuity, refractive error, ocular alignment, and stereopsis.

Main Results:

• Significant improvement in ocular alignment (esotropia reduced from 37.92Δ to 2.76Δ).
• Enhanced uncorrected visual acuity (logMAR from 0.46 to 0.32).
• Increased stereopsis from 15.3% to 84.6% post-surgery, with no decrease in any patient.

Conclusions:

• Hyperopic excimer corneal refractive surgery is effective in improving ocular alignment in patients with accommodative esotropia and amblyopia.
• The procedure also enhances uncorrected visual acuity and stereopsis.
• Corneal refractive surgery offers a viable option for managing complex pediatric eye conditions.
