The First Results of New Russian Lens Exchange IOL in Patients with High Myopia

Purpose: To evaluate safety, precision and stability of refractive results after phacoemulsification with implantation of NanOptica (Russia) IOL like a method for high myopia correction.

Patients and methods. 4 eyes of 2 patients aged 34 and 81 y.o. with high myopia: sph -6.5D — sph -12.0D (mean -9.12Д±2.39) were operated by phacoemulsification with hydrophylic IOL “Aquamarine” NanOptica (Russia) implantation. In first case operation was performed in young female, for correction of myopia with clear lens, the target was about -2.0 D. The second patient was treated for mature cataract by the same method. Study included evaluation UCVA, UCVA, Autorefractometry, IOP measurement, IOL master, ultrasound biometry, slit lamp examination, fundus examination, keratotopography, Cirrus OCT of posterior segment. Pre op mean UCVA (Decimal) 0.0475 (0.04–0.05 ), mean ВCVA 0.73 (0.4–1.0). Biometry (А method) from 26.82 mm to 28.49 mm, average 27.48 mm ±0.72. For IOL calculation we used SRK/T formula. The standard phacoemulsification was performed. Incision 2.4 mm. Injector Comfort C, RET, (Korea) was used for IOL delivery into the eye. There were no difficulty with IOL positioning in cartridge, injection in the eye and centration. Follow up period was 4 months. Study was performed at International Center for Ophthalmology in Moscow, Russia.

Results: Early postoperative period was without any complications. Post op mean UCVA (Decimal) was 0.66±0.27 (0.4–0.9), mean ВCVA — 0.95±0.05 (0.9–1.0). Target refraction corresponded to predetermined values: sph -1.75D–0.0 D (average -0.81). 34 years old patient had signs of posterior capsule fibrosis I st. after 3 months after operation. It didn’t affect at the visual acuity.

Conclusion: First successful results of IOL “Aquamarine” Naooptica (Russia) implantation were reached. Refractive target have been achieved. Aquamarine can be recommend for correction in patients of different age with high myopia patients. Future follow-up study is required.
