Usefulness of Implantation of Diffractive Multifocal Intraocular Lens in Eyes with Long Axial Lengths

Abstract

Purpose. This study retrospectively analyzed the postoperative visual functions of myopic eyes implanted with multifocal intraocular lens (IOL) to evaluate the efficacy of multifocal IOL in highly myopic eyes. Methods. We studied 61 patients (96 eyes) who were implanted with multifocal IOL ZMA00 or ZMB00 (Abbott Medical Optics). The patients were stratified into two groups by axial length: 26 mm or above (AL ≥ 26 group) and below 26 mm (AL < 26 group). Postoperative corrected and uncorrected distance (5 m) and near (30 cm) visual acuity (VA), contrast sensitivity, and depth of focus were compared between two groups. Results. In the AL ≥ 26 group and the AL < 26 group, the mean ± standard deviation uncorrected distance logMAR VA at 12-month postoperative follow-up was −0.04 ± 0.11 and −0.01 ± 0.14, respectively; and the corrected distance VA was −0.17 ± 0.08 and −0.14 ± 0.07, with no significant differences between two groups (p = 0.558 and 0.101; Mann-Whitney U test). For near VA, the corresponding uncorrected VA was 0.06 ± 0.08 and 0.05 ± 0.09; and distance-corrected VA was 0.01 ± 0.06 and 0.01 ± 0.02, with no significant differences between two groups (p = 0.572, and 0.157; Mann-Whitney U test). Conclusion. The present study demonstrates that it is possible to achieve good uncorrected near and distance VA following implantation of multifocal IOL in eyes with long axial lengths.

<p>Implantation of a Trifocal Intraocular Lens in High Myopic Eyes with Nasal-Inferior Staphyloma</p>

“…However, as we have introduced, the use of multifocal IOLs for presbyopia correction in eyes with long axial lengths has been increasing due to the good outcomes reported previously by several authors using different IOL models. 12,13,15,16 Our results revealed good visual acuity outcomes for both groups of patients, long eye and nasal-inferior staphyloma. Safety and efficacy indexes were larger than 1.0 in all cases.…”

“…Slight differences between studies may come from the use of a different multifocal IOL, different follow-up, and also for being higher myopic eyes in the case of Martiano and Cochener. 14 Ogawa et al 15 analyzed the 12-month postoperative outcomes found in 32 eyes implanted with the ZMA00 or the ZMB00 IOL. The mean axial length in this group was 27.38 mm, ranging from 26.06 to 29.24 mm.…”

“…Martiano and Cochener 14 evaluated 52 high myopic eyes with the AT LISA bifocal IOL showing favourable results at 6 years (26.54-30.7 mm axial length, 0-14 D IOL power, and 49-69 years). Ogawa et al 15 demonstrated good visual acuity outcomes in 32 eyes implanted with the ZMA00/ ZMB00 IOL (26.06-29.24 mm axial length, and 40-71 years). And recently, Zhu et al 16 found in 28 eyes implanted with the ZMB00 IOL good visual acuity comparable to emmetropic eyes but reporting that the myopic eyes presented inferior decentration and a decrease visual quality (>24.5 mm axial length, and a mean of 68.17 ±8.24 years).…”

Visual Performance after Bilateral Implantation of a Four-Haptic Diffractive Toric Multifocal Intraocular Lens in High Myopes

“…Alfonso et al [ 32 ] reported better results for distance and near VAs and CS in a group of low rather than highly myopic eyes after the implantation of the nontoric ReSTOR SN60D3 multifocal IOL (Alcon Laboratories Inc.). Ogawa et al [ 21 ] compared the distance and near VAs and CS of Tecnis multifocal IOL (Abbott Medical Optics, Inc., Santa Ana, CA) between eyes with an AL <26 mm and ≥26 mm and found no significant differences between groups. Neither study reported monocular intermediate VA or quantified visual symptoms.…”

“…у пациентов с миопией высокой степени в исследовании T. Ogawa с соавт. [4] сообщается, что 81% пациентов (из 61 пациента, 96 глаз) обходились без использования очков в послеоперационном периоде.…”
