Abstract
Purpose To confirm the safety, efficacy, and predictability of the surgical correction of moderate to high myopia by the ICM V3 and ICM V4 implantable contact lenses (ICLs), with emphasis on vaulting, intraocular pressure (IOP), and pigment dispersion.Setting University Eye Hospital, Lausanne, Switzerland.Methods Thirty-two eyes had implantation of an ICL. In 22 eyes with a mean spherical equivalent (SE) of −11.5 diopters (D), the target was emmetropia; in 10 eyes with a mean SE of −22.3 D, the goal was a reduction in the myopia. Nineteen eyes received the ICM V3 ICL and 13, the ICM V4 ICL. The mean follow-up was 7.4 months.Results The mean postoperative SE in the 32 eyes was –2.16 D. Best spectacle-corrected visual acuity was maintained or improved in all eyes. In the 22 eyes targeted to achieve emmetropia, 10 (45%) were within ±1.00 D; 15 (68%) had an uncorrected visual acuity of 20/40 or better and 4 (18%), of 20/20 or better. Vaulting of the ICL over the crystalline lens was more pronounced with the V4 than with the V3, and the difference was statistically significant. Subtle, localized anterior subcapsular opacification was encountered in 4 eyes. In 3 of them, the ICL (model V3) vaulting was minimal and 1 ICL (model V4) did not show any vaulting. Eighteen eyes had an IOP higher than the preoperative level, and the difference was statistically significant. No correlation was seen between final IOP and vaulting. Pigment dispersion on the ICL did not appear to be related to vaulting or ICL thickness.Conclusion Implantation of an ICL was effective in correcting moderate to high myopia of up to –17.50 D. Although the procedure appears to be safe, the predictability of the refractive outcome must be improved. The new generation of ICLs for myopia (ICM V4) offers a better vault over the crystalline lens than the older models (ICM V3), which should decrease the risk of cataract. No explanation was found for the IOP increase in several eyes 3 months or more after surgery.

In 22 eyes with a mean spherical equivalent (SE) of −11.5 diopters (D), the target was emmetropia; in 10 eyes with a mean SE of −22.3 D, the goal was a reduction in the myopia. Nineteen eyes received the ICM V3 ICL and 13, the ICM V4 ICL. The mean follow-up was 7.4 months.Results The mean postoperative SE in the 32 eyes was –2.16 D. Best spectacle-corrected visual acuity was maintained or improved in all eyes. In the 22 eyes targeted to achieve emmetropia, 10 (45%) were within ±1.00 D; 15 (68%) had an uncorrected visual acuity of 20/40 or better and 4 (18%), of 20/20 or better. Vaulting of the ICL over the crystalline lens was more pronounced with the V4 than with the V3, and the difference was statistically significant. Subtle, localized anterior subcapsular opacification was encountered in 4 eyes. In 3 of them, the ICL (model V3) vaulting was minimal and 1 ICL (model V4) did not show any vaulting. Eighteen eyes had an IOP higher than the preoperative level, and the difference was statistically significant. No correlation was seen between final IOP and vaulting. Pigment dispersion on the ICL did not appear to be related to vaulting or ICL thickness.Conclusion Implantation of an ICL was effective in correcting moderate to high myopia of up to –17.50 D. Although the procedure appears to be safe, the predictability of the refractive outcome must be improved. The new generation of ICLs for myopia (ICM V4) offers a better vault over the crystalline lens than the older models (ICM V3), which should decrease the risk of cataract.
