To summarize advancements in intraocular lens (IOL) power calculation for cataract surgery in patients with a history of radial keratotomy (RK).
Approach:
Literature Review: A narrative review was conducted using the PRISMA framework to evaluate existing literature on IOL power calculation in post-RK patients, focusing on corneal changes, IOL formula accuracy, and novel IOL technologies.
Key Findings:
Conventional IOL formulas yield only about 50% accuracy in achieving target refraction within ±0.5 D for post-RK eyes.
Interpretation:
The review summarizes the need for specialized approaches in IOL power calculation for post-RK patients due to their unique corneal characteristics.
Limitations:
The review does not include a formal systematic meta-analysis.
Only studies published in English and original research articles were included.
Conclusion:
The advancements in IOL calculation methods and technologies provide improved options for cataract surgery in post-RK patients.
