Summary
Radial keratotomy (RK) surgery can lead to vision complications and visual fluctuations years later. Due to these risks and increased eye injury potential, RK is not recommended for active duty military personnel.
Area of Science:
- Ophthalmology
- Refractive Surgery
Background:
- Radial keratotomy (RK) is a surgical procedure to correct refractive errors by flattening the cornea.
- While intended to improve vision, RK can result in various short-term and long-term complications.
Purpose of the Study:
- To evaluate the long-term visual outcomes and potential complications associated with Radial Keratotomy.
- To determine the suitability of RK for individuals with high visual demands, such as military personnel.
Main Methods:
- Review of existing literature on Radial Keratotomy outcomes and complications.
- Analysis of visual acuity, refractive stability, and incidence of adverse events post-RK.
Main Results:
- Only 50% of patients achieve 20/20 uncorrected vision 2-3 years post-RK.
- Persistent diurnal vision fluctuations (2-5 lines) and potential loss of best-corrected vision (1%) can occur.
- Increased risk of corneal rupture and disabling glare are significant concerns.
Conclusions:
- Radial keratotomy carries risks of persistent visual disturbances and complications.
- The visual demands of military service, especially for aviators, are incompatible with RK.
- RK should not be performed on active duty soldiers, and those with prior RK should not be enlisted.
