Visual results after refractive surgery

For LASIK, the American PROWL studies, cited in the American Academy of Ophthalmology guidelines ^[1], report that at three months, 99% and 96% of patients reach at least 10/10 uncorrected vision with both eyes. The 98% reported by Vision Laser Geneva falls within this high range.

A study on FemtoLASIK reports a mean uncorrected acuity of 0.006 logMAR at three months, about 9.9/10 (delos Reyes et al., 2024).

A European study reports 0.01 logMAR at six months, about 9.8/10 (Margarit et al., 2024).

Several publications also report a high proportion of eyes reaching 10/10 uncorrected. In a prospective study by Adib-Moghaddam and colleagues ^[2], this proportion reaches 93.8% at eighteen months. More recently, Shi and colleagues ^[3] report, at six months, 96.8% for low to moderate myopia and 92.3% for high myopia. These results show in particular how much the initial degree of myopia matters when interpreting the figures.

For ICL implants, the American multicentre trial of the EVO/EVO+ models ^[4] reports that at six months, 87.6% of eyes reach at least 10/10 uncorrected. An analysis of the moderate-myopia subgroup ^[5] finds a proportion of 94.5%.

In another multicentre study of patients aged 45 and over ^[6], 86% of eyes reach this level at the last check-up, after an average follow-up of about two years. Results therefore vary with patient characteristics and length of follow-up.

A study of Supracor PresbyLASIK combined with micromonovision ^[7] reports, at twelve months, a mean uncorrected distance acuity with both eyes open of about 9.5/10.

This is an average, however, and cannot be compared directly with the proportion of patients reaching 10/10 reported by Vision Laser.
