We reviewed a consecutive series of 194 myopic eyes which received minimally invasive radial keratotomy (mini-RK) by which eight radial incisions are made on the corneal surface. Correction within ±0.5 diopters (D) was achieved in 80% of eyes with initial myopia of -4.5D or less and within ±1.0D in 93% of these eyes. In eyes with myopia of more than -4.5D, correction within ±0.5D was achieved in 37% and within ±1.0D in 63% of eyes. Glare or starburst resulted in about 50% of eyes corrected by 4.5D or more. There was no decline in contrast sensitivity when the optical zone was 3.5mm. Significant decline resulted in day and night vision when the optical zone was 3.0mm. The findings show that mini-RK is safe and effective when corrected by 4.5D or less when the optical zone is 3.5mm or more.
