Abstract Details

Purpose:

To evaluate long term outcomes of Implantable Collamer Lens (ICL) implantation (V4) for high myopia with and without astigmatism, and to analyze visual outcomes, safety factors and review complications.

Setting:

Cornea & Refractive Service, Shroff Eye Centre, A-9, Kailash Colony, New Delhi - 110048, India.

Methods:

223 eyes of 114 patients with a mean age of 45.26±1.16 years underwent ICL implantation for myopia ranging from -8.75 to -21.50 D sphere. All patients had a minimum 12 year follow up. At 13 years the main outcome measures were UDVA, CDVA, predictability, manifest refractive errors, vault, endothelial cell loss and complication rates. Contrast sensitivity, and patient satisfaction was also assessed.

Results:

UDVA at 13 years was 20/20 or better in 65.28% eyes and 20/40 or better in 81.13% eyes. Safety-index was 1.03 and efficacy-index was 0.99. Mean spherical equivalent was -0.87±2.13D. Mean vault height was 573.6±226.1 microns at 6-months decreasing to 392.2±137.4 at 13 years. There was no significant IOP increase over time. Lens opacities developed in 32 eyes (14.3%). Mean vault in the lens opacity group was significantly lower (p = .026) than the clear lens group. Patients who had ICL at a younger age (<30 years) never developed lens opacities. No significant decrease in endothelial cell density was observed.

Conclusions:

ICL implantation for high myopia is safe and effective over a long term period with long term stability, good refractive outcomes and preserved corneal integrity. The average Quality of Vision value improved with high patient satisfaction.
