Purpose

To evaluate preoperative characteristics, indications, safety, predictability, accuracy and visual outcomes of EVO ICL (STAAR Surgical) implantation in patients with low to moderate myopia.

Setting

Pallikaris department of refractive surgery, Asian Eye Hospital, A Tertiary Care Eye Hospital, Pune, India

Methods

This retrospective analytical study was conducted at a tertiary private ophthalmology center. A total of 361 eyes of patients aged 20–50 years with spherical equivalents ranging from −1.00 D to −6.00 D underwent EVO ICL implantation. Data were analyzed on preoperative parameters, indications for choosing ICL over corneal laser refractive surgery, and postoperative outcomes including refractive predictability, safety, stability, intraocular pressure (IOP), and vault, with a follow-up of up to one year.

Results

Of the 361 eyes, 91 belonged to males and 130 to females, with a mean age of 29.05 years and mean spherical equivalent of −4.36 D. Mean anterior chamber depth was 3.26 mm, and mean central corneal thickness was 499.35 µm. Among them, 23 eyes had normal corneal thickness and shape (laser-eligible patients who elected ICL), 223 had thin or borderline tomography, 96 were keratoconus suspects, 10 had diagnosed keratoconus, and 1 had a thin cornea with normal tomography.

Preoperative mean logMAR visual acuities were: UDVA 1.0634, UNVA 0.1104, CDVA 0.1039, and CNVA 0.1102. Postoperatively, the values improved to UDVA 0.0227, UNVA 0.1099, CDVA 0.0238, and CNVA 0.1100. None of the patients reported any complications upto 1 year of follow up.

Conclusions

This is probabaly the largest series reporting EVO ICL outcomes in low to moderate myopia globally. The results demonstrate excellent visual acuity, high safety and efficacy indices of EVO ICL in patients with or without unsuitable corneal charactistics.
