5 Key Takeaways

• 1

  The study compared visual outcomes of mini-scleral lenses and small-diameter rigid GP lenses in moderate-to-severe keratoconus patients.

• 2

  Both lens types significantly improved best-corrected visual acuity, with RGP lenses showing lower irregular astigmatism and better topographic indices.

• 3

  Topographic indices like center-surround index and irregular astigmatism index were valuable in predicting lens suitability and visual improvement.

• 4

  Mini-scleral lenses were particularly beneficial for patients with apical scarring or highly decentered cones.

• 5

  The study's limitations include its retrospective design, small sample size, and potential selection bias affecting results.
