Keratectasia After Presbyopia Treatment With INTRACOR

Area of Science:

• Ophthalmology
• Corneal Surgery
• Refractive Error Correction

Background:

• INTRACOR is a laser-based refractive surgical procedure designed to correct presbyopia.
• Presbyopia, the age-related loss of near focusing ability, affects a significant portion of the adult population.
• While effective, refractive surgical techniques carry potential risks and complications that require careful monitoring.

Observation:

• A 58-year-old male presented with decreased vision in his left eye.
• The patient had previously undergone INTRACOR presbyopic treatment in the affected eye five years prior.
• Clinical examination revealed an ectatic cornea with characteristic concentric scars and significant anterior and posterior elevations on corneal topography.

Findings:

• The patient's best-corrected visual acuity (BCVA) was 20/40 at presentation.
• Corneal topography confirmed marked keratectasia, with thinning at the site of maximal elevation.
• Temporary management with hybrid contact lenses improved BCVA to 20/30.

Implications:

• This case underscores corneal ectasia as a potential complication following INTRACOR presbyopic treatment.
• Ophthalmologists should maintain a high index of suspicion for ectasia in patients with a history of refractive surgery presenting with visual deterioration.
• Long-term monitoring and awareness of rare but serious complications are crucial for patient safety in refractive surgery.
