Summary
Photorefractive keratectomy (PRK) effectively corrects hyperopia after radial keratotomy. This excimer laser treatment significantly improves uncorrected visual acuity in patients experiencing this common complication.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Excimer Laser Technology
Background:
- Progressive hyperopia is a frequent complication following radial keratotomy.
- This condition can significantly impair uncorrected visual acuity.
Purpose of the Study:
- To evaluate the efficacy of excimer laser photorefractive keratectomy (PRK) for correcting hyperopia after radial keratotomy.
- To assess the visual outcomes and safety of this treatment modality.
Main Methods:
- Ten eyes of ten consecutive patients with post-radial keratotomy hyperopia (+1.75 to +4.00 D) were treated.
- The Nidek Model EC-5000 excimer laser with its hyperopia module was utilized.
- Preoperative uncorrected visual acuity averaged 0.38 (20/60+).
Main Results:
- Post-PRK, mean uncorrected visual acuity improved to 0.72 (20/30+).
- The treatment demonstrated a significant enhancement in visual function.
- One eye experienced haze exceeding 2+, with no other reported complications.
Conclusions:
- Excimer laser PRK is a valuable and effective method for correcting hyperopia that develops after radial keratotomy.
- This procedure offers a promising solution for visual rehabilitation in this patient group.
