Summary

Topical steroid treatment can reverse refractive regression after myopia correction surgery (photorefractive keratectomy). About half of treated eyes achieved stable refraction close to the intended target.

Area of Science:

  • Ophthalmology
  • Refractive Surgery
  • Corneal Surgery

Background:

  • Photorefractive keratectomy (PRK) is a common procedure for myopia correction.
  • Refractive regression can occur post-PRK, impacting visual outcomes.
  • Topical steroids are used to manage inflammation and promote healing after refractive surgery.

Purpose of the Study:

  • To assess the efficacy of topical steroid treatment in reversing myopic refractive regression after PRK.
  • To evaluate the impact of steroid treatment on visual acuity and refractive stability.

Main Methods:

  • Prospective study of 289 eyes undergoing PRK for myopia.
  • Identified 23 eyes with myopic regression (≥0.75 D).
  • Administered topical steroids to eyes with regression and monitored refraction and visual acuity for ≥6 months.

Main Results:

  • Twelve eyes with regression had ≥18 months follow-up.
  • Eight of these eyes achieved uncorrected visual acuity of 20/40 or better.
  • Six eyes achieved a final refraction within 1.00 D of the intended correction.

Conclusions:

  • Topical steroid treatment can successfully reverse refractive regression in some eyes post-PRK.
  • Approximately half of the eyes treated for regression achieved stable refraction near the target.
  • Steroid therapy offers a potential solution for managing refractive instability after PRK.
