Visual Performance of Tecnis ZM900 Diffractive Multifocal IOL after 2500 Implants: A 3-Year Followup

Abstract

Purpose. To evaluate visual performance for near, intermediate, and distant vision; complaints of photic phenomena, and patient satisfaction with the new diffractive multifocal IOL used in eyes which underwent phacoemulsification. Methods. Two thousand and five hundred consecutive eyes undergoing Tecnis ZM900 multifocal IOL implantation were included in this retrospective analysis. The minimum followup of 3 months was required after the surgery. Patients were assessed for uncorrected near visual acuity (UNVA) at a fixed distance (33 cm), uncorrected intermediate visual acuity (UIVA) at 60 cm, and uncorrected distance visual acuity (UDVA). Using a subjective questionnaire, patients satisfaction, their independence from using glasses, and the perception of glare and halo phenomena were also evaluated at the last follow-up. Results. Two thousand and five hundred eyes of 1558 patients underwent cataract surgery and Tecnis ZM900 multifocal IOL implantation. Four hundred and eighty seven patients (31.3%) were men, and 1071 (68.7%) were women. The mean age of the patients was 66.17 years. A UDVA of 20/30 or better was achieved by 85% of eyes. A UNVA of J1 was achieved by 93.7% of eyes and that of J2 or better was achieved by 98%. A UIVA of J4 or better was achieved by 65% and J5 or better was achived by more than 82.8% of the eyes in the study. Glare and halos were reported as severe by only 6.1% and 2.12% of patients, respectively. Ninety seven percent reported complete spectacle independence and 88% stated that they are totally satisfied with their quality of vision and would choose to have the same lens implanted again after the first implant. Five percent of the eyes in the study needed a second procedure (enhancement) to achieve a better visual result. No patient underwent lens exchange. Conclusion. Excellent near, intermediate, and distant vision was observed in patients implanted with the Tecnis ZM900 diffractive multifocal IOL. Spectacle independence and a minimum occurrence of photic phenomena make this IOL an excellent option in patients with cataract.

Clinical evaluation of the OptiVis™ multifocal intraocular lens

“…7 In some models, the incidence of glare and halo have been reported to range from 6% to 40% for glare, and from 11% to 44% for halo. [8][9][10][11] Although, in recent years, the newest multifocal IOLs are typically associated with lower incidence of these phenomenon, [12][13] a recent study of 2500 patients reported that 6.1% of patients treated with Tecnis™ (Abbott Medical Optics Inc., Santa Ana, CA, USA) multifocal IOLs experience glare and 2.1% experience halo. 14 In the present study, the incidence of glare and halo was considerably lower than many previous reports, with a combined incidence of only 6.7%, and no severe incidence reported.…”

“…3 Buna karşılık son yıllardaki yayınlarda yeni konsept multifokal GİL'lerde orta mesafe görme keskinliğinde ve kontrast duyarlılıkta daha iyi sonuçlar bildirmişler, halo ve kamaşma problemlerinde ise azalmalar olduğu tespit edilmektedir. [16][17] 2500 hastaya Tecnis™ (Abbott Medical Optics Inc., Santa Ana, CA, USA) multifokal GİL uygulanmış yeni sayılabilecek bir çalışmada %6,1 hastada kamaşma, %2,1 hastada halo görülmüştür. 16 Bizim çalışmamızda operasyondan 3 ay sonra hiçbir hastada şiddetli halo ve kamaşma şikayeti olmamıştır.…”

Fotik şikayetlerin azalmasında yeni GİL'in dizaynı çok önemlidir.…”

“…It has an aspheric anterior surface with +4 D near add (+3.0 D at the spectacle plane). A retrospective study on the earlier version of this IOL found an uncorrected distance visual acuity of 20/30 in 85% of eyes and an uncorrected near visual acuity of J1 in 93.7% of 2500 eyes, 3 years postoperatively [35]. Glare and halos were reported as severe by 6.1 and 2.12% of patients, respectively.…”
