Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Refractive Surgery

Background:

  • Radial keratotomy (RK) is a surgical procedure to correct myopia.
  • Evaluating surgeon experience is crucial for patient safety and outcomes.

Purpose of the Study:

  • To assess the presence and impact of a learning curve in radial keratotomy (RK).
  • To compare surgical outcomes between early and experienced RK procedures.

Main Methods:

  • Prospective evaluation of two groups of 20 eyes undergoing RK.
  • Group 1: RK performed with no prior experience; Group 2: RK performed after 250 cases.
  • Groups matched for age, sex, and preoperative refractive error.

Main Results:

Related Experiment Videos

  • Nine microperforations occurred in the initial 20 RK cases (Group 1).
  • No microperforations were observed in the experienced group (Group 2).
  • Postoperative refractions and uncorrected visual acuities were similar between both groups.

    • Conclusions:

    • Microperforations in early RK cases did not adversely affect visual outcomes.
    • The surgeon's learning curve for RK was minimal, with no significant impact on results.
