Keratophakia and keratomileusis--clinical results

Area of Science:

• Ophthalmology
• Refractive Surgery

Background:

• High anisometropia presents a significant challenge in refractive error correction.
• Traditional surgical methods for high refractive errors have limitations.

Purpose of the Study:

• To evaluate the efficacy and safety of keratophakia and keratomileusis for refractive error correction.
• To analyze corneal curvature changes, refractive outcomes, accuracy, stability, and complications.

Main Methods:

• Retrospective analysis of 158 patients undergoing keratophakia or keratomileusis.
• Data collection included corneal curvature, refraction, visual acuity, and complications.

Main Results:

• Both techniques effectively corrected aphakic hyperopia and high myopia (up to 16 diopters).
• Lamellar refractive keratoplasty did not significantly impair visual acuity; most myopic patients improved.
• Postoperative astigmatism was minimal, and corneal curvature remained stable.
• Refractive inaccuracy was the primary limitation, though complications were minimal.

Conclusions:

• Keratophakia and keratomileusis are viable options for correcting significant refractive errors.
• These lamellar refractive keratoplasty procedures offer good stability and visual outcomes.
• Improving refractive accuracy is crucial for optimizing patient results.
