Outcomes of implantable collamer lenses (ICL), femtosecond-assisted laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) for correction of hyperopia

Purpose

To evaluate the outcomes of implantable collamer lenses (ICL), femtosecond-assisted laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) for treatment of hyperopia.

Settings

Tertiary eye center.

Design

Case series.

Methods

All patients with hyperopia managed by ICL (Gr 1), LASIK (Gr 2) and PRK (Gr 3) in 2014 to 2019 were reviewed for safety and efficiency, predictability and spherical equivalent (SE) pre-operatively then at one and 12 months after surgery.

Results

Total of 99 hyperopic eyes, management Gr 1, Gr 2 and Gr 3 included 26, 57 and 16 eyes respectively. The mean pre-operative manifest refraction spherical equivalent (MRSE) was +5.13D, +3.15D D, +2.39D for Gr 1, Gr 2 and Gr 3 respectively. One year after surgery, the mean MRSE was −0.23D, +0.34D and +0.08D respectively (p = 0.065). The safety index was 1.0 and efficacy index was 0.89 in all groups. The predictability for achieving ±1.0 D SE was 95.8%, 92%, and 93.3% in Gr 1, Gr 2 and Gr 3 respectively. Peripheral faint corneal haze was noticed in PRK group (P = 0.05).

Conclusions

All three procedures had excellent visual gain and stable refraction at one year after surgeries with low complication rates. They seem to be safe, efficient and predictable procedures.
