Summary

Refractive corneal surgery, including keratotomy and epikeratoplasty, has rapidly advanced. New techniques like intrastromal hydrogel implants and lens extraction offer improved vision correction for myopia and astigmatism.

Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Vision Correction

Background:

  • Refractive corneal surgery has seen significant growth in the U.S. over the past eight years.
  • Common procedures include keratotomy for myopia/astigmatism and epikeratoplasty for aphakia.

Purpose of the Study:

  • To review the current landscape of refractive corneal surgery.
  • To highlight emerging and established surgical techniques for vision correction.

Main Methods:

  • Review of common refractive surgical procedures: keratotomy, epikeratoplasty.
  • Discussion of ongoing clinical studies: intrastromal hydrogel implants.
  • Analysis of lens-based procedures: clear lens extraction, intraocular lens implantation for high myopia.
  • Consideration of astigmatism correction during cataract surgery.

Main Results:

  • Keratotomy and epikeratoplasty are established procedures for myopia, astigmatism, and aphakia.
  • Intrastromal hydrogel material implantation is under clinical investigation.
  • Clear lens extraction and intraocular lens implantation are increasingly used for myopia correction.
  • Addressing corneal astigmatism during cataract surgery enhances post-operative visual acuity.

Conclusions:

  • Refractive corneal surgery has evolved significantly, offering diverse options for vision correction.
  • Emerging technologies and refined surgical approaches continue to improve patient outcomes.
  • Management of astigmatism alongside cataract surgery is crucial for optimal visual results.
