[Orthoptic indications for radial keratotomy: esophoric myopia]

Area of Science:

• Ophthalmology
• Optometry
• Vision Science

Background:

• Refractive surgery planning typically focuses on correcting refractive errors.
• Binocular vision anomalies, such as aniseikonia, are recognized considerations.
• The role of other binocular factors in refractive surgery outcomes requires further elucidation.

Observation:

• Exophoria, a tendency for eyes to turn outward, can be a contraindication for refractive surgery.
• Esophoria, a tendency for eyes to turn inward, presents a different clinical scenario.
• The management of significant esophoria often involves prismatic correction.

Findings:

• Refractive surgery may be indicated in patients with significant esophoria at both near and distance visual tasks.
• Successful refractive surgery in esophoric patients could potentially obviate the need for corrective prisms.
• This suggests a potential therapeutic role for refractive surgery in managing specific binocular vision disorders.

Implications:

• Refractive surgery guidelines should incorporate comprehensive binocular vision assessments.
• Patients with esophoria may be suitable candidates for refractive surgery, offering an alternative to prismatic correction.
• This approach could improve visual quality and reduce reliance on optical aids for esophoric individuals.
