he implantation of a multifocal intraocular lens (IOL) after the extraction of cataract has been reported as an alternative to improve the near vision performance and the quality of life of some patients. [1][2][3][4][5][6] The use of multifocal IOLs offers a significant opportunity to improve distance and near vision. However, these improved IOL designs are insufficient if the lens does not suit the lifestyle of patients recovering their vision at all distances, including intermediate distance.4-8 Many IOL technologies are commercially available for implantation after cataract surgery and several studies have reported that diffractive multifocal IOLs with an aspheric profile perform better than refractive multifocal or accommodating IOLs in terms of near visual acuity. On the other hand, aspheric profiles give better optical quality in comparison to spherical profiles. [8][9][10][11][12][13] Recently, a new multifocal model IOL has been introduced in clinical practice combining two diffractive apodized profiles that can provide three foci for distance, near, and intermediate vision.14 There are few publications describing the outcomes after the implantation of a trifocal intraocular lens and some of these have limited samples. [15][16][17] Additionally, this new IOL offers the possibility to be implanted through a sub-2-mm incision, accomplishing the advantages of microincisional cataract surgery (MICS).The aim of the current study was to evaluate the visual and the intraocular performance of this new trifocal IOL in eyes implanted following cataract surgery performed through MICS. PATIENTS AND METHODS PatientsIn this prospective, consecutive, non-comparative interventional study, we included 40 eyes of 20 patients with T ABSTRACT PURPOSE: To evaluate the visual outcomes of patients with a new diffractive trifocal intraocular lens (IOL). METHODS:A trifocal diffractive Fine Vision IOL (Physiol, Liege, Belgium) was implanted after microincision cataract surgery (MICS) in 40 eyes of 20 patients with bilateral cataract. The monocular and binocular visual performance and the refractive status were assessed, as well as the defocus curve and contrast sensitivity at 1 and 6 months postoperatively. RESULTS:The monocular visual outcomes (logMAR) at 6 months postoperatively were uncorrected distance visual acuity 0.18 ± 0.13, uncorrected near visual acuity 0.26 ± 0.15, and uncorrected intermediate visual acuity 0.20 ± 0.11. With the best distance correction, the visual outcomes were 0.05 ± 0.06 for corrected distance visual acuity, 0.16 ± 0.13 for distance corrected near visual acuity, and 0.17 ± 0.09 for distance corrected intermediate visual acuity. Binocular defocus curve at 6 months shows a wide range of useful vision with 0.19 ± 0.08 (logMAR) at -1.50 diopter defocus. The monocular contrast sensitivity under scotopic conditions (3 cd/m 2 ) was within normal range for a population older than 60 years. CONCLUSION:The trifocal Fine Vision IOL can restore vision at different distances after cataract surgery, specifically...

Amaç: Acri.LISA 356D bifokal göz içi lensi implantasyonu yap›lan hastalarda görsel sonuçlar›n de¤erlendirilmesi. Gereç ve Yöntem: Fakoemülsifikasyon tekni¤i ile katarakt ekstraksiyonu yap›lan 26 hastan›n 33 gözüne difraktif multifokal G‹L Acri.LISA 356D implantasyonu yap›ld›. Ameliyat sonras› 1. ve 3. ayda tüm gözlerin ayd›nl›k (85 cd/m 2 ) ortamda ve karanl›k (5 cd/m 2 ) ortamda kontrast duyarl›l›klar›, düzeltmesiz ve düzeltmeli uzak, yak›n ve orta görme keskinlikleri ile gözlük ihtiyaçlar›, refraktif kusurlar›, yans›ma ve halo flikayetleri de¤erlendirildi. Sonuçlar: Hastalar›n yafl ortalamalar› 58,2±9,3 y›l idi. Çal›flmaya kat›lan 26 hastadan bilateral multifokal lens implante edilen 7 hastan›n 5'i kad›n 2'si erkek, tek gözüne lens implantasyonu yap›lan 19 hastan›n 8'i kad›n 11'i erkek idi. Ameliyat sonras› 3. ayda, uzak düzeltmeli olarak en iyi görme keskinli¤i uzakta 0,94±0,08, yak›nda 0,77±0,12 ve orta mesafede 0,67±0,10 idi. Uzak mesafe görme keskinli¤i; yak›n ve orta mesafe görme keskinli¤inden anlaml› derecede yüksekti. Yak›n mesafe görme keskinli¤i ise orta mesafe görme keskinli¤inden anlaml› derecede yüksek bulundu (p<0,05). Ameliyat sonras› otorefraktometre ile ölçülen ortalama sferik eflde¤er -0,85±0,55 D olarak tespit edildi. Kontrast duyarl›l›k seviyeleri 1. ayda özellikle yak›n mesafede olmak üzere hem fotopik hem de mezopik ortamda düflük seyretti. 3. ayda yak›nda mezopik ortamda yüksek uzaysal frekanslar için bu düflüklük aynen devam etti. Ameliyat sonras› astigmatik kusuru yüksek olan hastalarda halo flikayetine daha yüksek oranda rastland›. Hastalarda %74 oran›nda uzak için gözlük kullanma ihtiyac› do¤arken, gözlük kullanma oran› %15 de kald›. Tart›flma: Bifokal hibrid G‹L olan Acri.LISA 356D, fotopik ve mezopik koflullarda uzak ve yak›nda görme keskinli¤i ve kontrast sensitivite aç›s›ndan baflar›l› olmas›na ra¤men ara mesafede ayn› oranda baflar›l› de¤ildir. ( Material and Method:Thirty-three eyes of 26 patients who had undergone cataract extraction by phacoemulsification technique were implanted with Acri.LISA 356 D IOL. All eyes were tested both at far and near distance at mesopic and photopic room light levels (5 and 85 cd/m 2 ), in the following 1st and 3 rd months after the operation. All eyes were tested for far, intermediate and near visual acuity, contrast sensitivity, refractive errors, glare and visual complaints, and need for spectacles. Results: The mean age of the patients was 58.2±9.3 years. Out of the 26 patients who participated in the study, nineteen (8 female, 11 male) had unilateral and 7 patients (5 female, 2 male) had bilateral implantation. At 3-month postoperative visit, the mean best-corrected distance visual acuity was 0.94±0.08, the best distance-corrected near visual acuity was 0.77±0.12 and the best distance-corrected intermediate (70cm.) visual acuity was 0.67±0.10. Distance visual acuity was significantly better than intermediate and near visual acuities, while near visual acuity was statistically significantly better than intermediate visual acuity (p<0.05 for ...

“…Many studies [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] have evaluated distance and near visual acuity after hybrid multifocal IOL implantation (Tables 1 and 2). In most of these studies, average monocular distance visual acuity (VA) and corrected for distance near vision (NV) after multifocal IOL implantation were better than 0.1 logMAR (about 6/7.5), with most eyes maintaining or improving both VA and distance corrected near vision.…”

During the past years, the wish to become independent of spectacles has been growing among cataract and presbyopic patients due to many factors, such as the increase in near visual demands, the aesthetic need for a spectacle-free image and ageing of refractive surgery patients, among others. This review assesses recently published studies that analyse visual and optical performance through different metrics of eyes implanted with multifocal intraocular lenses (IOLs), particularly hybrid IOL designs. The published evidence suggests that hybrid multifocal IOLs provide very good outcomes in a number of visual and optical performance parameters. Patients implanted with this type of IOL obtain a satisfactory full range of visual functions, including patients of particular characteristics such as highly ametropic or post-LASIK.

Visual acuity comparison of 2 models of bifocal aspheric intraocular lenses

Abstract: The 2 multifocal aspheric IOL models gave similar and good high-contrast visual acuity at distance and near. Intermediate visual acuity, also comparable between IOL models, was better than published results of a spherical IOL model.
