Objective:

To evaluate the effectiveness of algorithm-assisted refraction compared to conventional methods in patients with irregular corneas fitted with scleral lenses.

Key Findings:

• Algorithm-based refraction yielded a more positive spherical equivalent than conventional refraction.
• Both methods showed comparable high and low-contrast visual acuity.
• The study suggests algorithm-based refraction is a viable alternative for over-refraction in patients with irregular corneas.

Interpretation:

The findings indicate that advancements in refraction technology can enhance visual correction accuracy, particularly for patients using scleral lenses.

Limitations:

• The sample size was small, limiting the generalizability of results.
• Variability in subjective refraction may be influenced by practitioner experience.

Conclusion:

Algorithm-assisted refraction may improve the fitting process for scleral lenses in patients with irregular corneas, warranting further research.
