Visual outcomes after implantation of a novel refractive toric multifocal intraocular lens
Arquivos Brasileiros de Oftalmologia, 2014
The goal of modern cataract surgery is to gain spectacle independence for distance, intermediate, and near vision, which can be achieved with the implantation of multifocal intraocular lenses (IOLs). However, approximately 15%-29% cataract patients have more than 1.50 diopters (D) of corneal or refractive astigmatism (1-3). A residual astigmatism error of 1.50 to 3.0 D after cataract surgery may decrease uncorrected visual acuity (UCVA) to 20/70 or 20/100 and may interfere with spectacle independence after multifocal IOL implantation (4). To overcome this problem, various surgical options to control astigmatism during cataract surgery are available (4,5). Patients with a considerable amount of corneal astigmatism who wish to undergo multifocal IOL implantation have several options, including a clear corneal cataract incision along the steep meridian (5) , astigmatic keratotomy (AK) (6,7) , opposite clear corneal incisions (8) , limbal relaxing ABSTRACT Purpose: To assess the postoperative outcomes of a novel toric multifocal intraocular lens (IOL) in patients with cataract and corneal astigmatism. Methods: This prospective nonrandomized study included patients with cataract, corneal astigmatism, and a motivation for spectacle independence. In all patients, a Rayner M-flex ® T toric IOL was implanted in the capsular bag. Three months after surgery, the distance, intermediate, and near visual acuities; spherical equivalent; residual refractive astigmatism; defocus curve; and contrast sensitivity were evaluated. A patient satisfaction and visual phenomena questionnaire was administered to all patients. Results: Thirty-four eyes of 18 patients were included in this study. Three months after surgery, the mean corrected distance visual acuity (logMAR) was 0.00 ± 0.08 at 6 m, 0.20 ± 0.09 at 70 cm, and 0.08 ± 0.11 at 40 cm. Uncorrected distance vision acuity was 20/40 or better in 100% eyes. The preoperative mean refractive cylinder (RC) was-2.19 (SD: ± 0.53). After a 3-month follow-up, the average RC was-0.44 D (SD: ± 0.27; p<0.001). Contrast sensitivity levels were high. At the last follow-up, 87.5% patients were spectacle-independent for near, intermediate, and distance vision, and approximately 44% patients reported halos and glare. Conclusion: Toric multifocal IOL implantation in patients with cataract and cor neal astigmatism using the Rayner M-flex ® T toric IOL was a simple, safe, and accurate option. This technology provides surgeons with a feasible option for meeting patient expectations of an enhanced lifestyle resulting from decreased spectacle dependence.
Clear Lens Extraction with Multifocal Apodized Diffractive Intraocular Lens Implantation
Ophthalmology, 2007
To assess efficacy, safety, predictability, and stability after clear lens extraction (CLE) with multifocal diffractive intraocular lens (IOL) implantation.Prospective, nonrandomized, masked observational case series (self-controlled).Two hundred twenty-four eyes of 112 consecutive patients after CLE with bilateral AcrySof ReSTOR Natural IOL implantation. Eyes were divided into myopic (mean spherical equivalent [SE], −6.01±2.71 diopters [D]) and hyperopic (mean SE, +3.86±2.52 D) groups.Monocular and binocular uncorrected distance visual acuity (VA), best-corrected distance VA, uncorrected distance near VA, and best distance-corrected near VA were recorded preoperatively and 6 months after surgery.Efficacy, safety, predictability, and stability.At 6 months postoperatively, uncorrected distance VA was 20/25 or better in 100% of the eyes. Efficacy indexes were 0.97 for myopic and 0.96 for hyperopic patients. No eye lost ≥2 lines of best-corrected distance VA; for the myopic group, 10 eyes gained 1 line, and 10 eyes gained ≥2 lines; for the hyperopic group, 20 eyes gained 1 line, and 15 eyes gained ≥2 lines. Safety indexes were 1.05 for myopic and 1.02 for hyperopic patients. All eyes were within ±1.00 D of the desired refraction. No eye lost >2 lines of best distance-corrected near VA; for the myopic group, 10 eyes lost 1 or 2 lines, 15 eyes gained 1 line, and 5 eyes gained 2 lines; for the hyperopic group, 8 eyes lost 1 or 2 lines, 20 eyes gained 1 line, and 16 eyes gained 2 lines. Safety indexes at near were 1.05 for myopic and 1.11 for hyperopic patients. Uncorrected distance near VA was better for hyperopic than myopic patients (0.95±0.08 vs. 0.88±0.15). Efficacy indexes at near were 1.03 for myopic and 1.10 for hyperopic patients.Clear lens extraction with multifocal IOL implantation is an effective procedure for correcting ametropia and presbyopia. Safety and efficacy indexes at distance were comparable in myopic and hyperopic patients. However, at near, both indexes were larger for hyperopic patients.

To assess visual outcomes after bilateral implantation of an apodized C3.0 diopter (D) addition power toric diffractive multifocal intraocular lens (IOL). SETTING: Five study sites in Europe and South America. DESIGN: Cohort study. METHODS: Patients had bilateral implantation of the AcrySof Ò IQ ReSTOR Ò C3.0 D toric multifocal IOL. Inclusion criteria were age from 21 to 70 years, need for bilateral cataract extraction or refractive lens exchange, and regular corneal astigmatism from 0.75 to 2.5 D. Six-month evaluations included spherical equivalent (SE), refractive and corneal cylinder, visual acuity at various distances, defocus testing, reading speed, and IOL rotation. RESULTS: Forty-four of 49 patients completed the 6-month visit. The mean SE (88 eyes) was 0.09 D G 0.49 (SD) at 6 months (G1.00 D in 95.2%). The mean refractive cylinder decreased from 1.07 G 0.71 D to 0.33 G 0.44 D (%0.50 D in 78.6% and %1.00 D in 92.9%). The mean binocular uncorrected visual acuity was 0.04 G 0.08 logMAR at preferred near (w39 cm), 0.07 G 0.09 logMAR at 40 cm, 0.09 G 0.11 logMAR at 60 cm, and 0.05 G 0.10 logMAR at 4 m. The mean corrected reading speed increased from 125.43 G 33.58 words per minute (wpm) to 132.68 G 23.69 wpm. The mean IOL rotation was 2.20 G 4.34 degrees. CONCLUSION: Six months after implantation of the toric multifocal IOL, patients had significantly reduced SE and refractive cylinder, good visual acuity across distances, increased reading speed, and minimal IOL rotation.

Purpose: To evaluate the safety and efficacy of a new multi-segmented refractive multifocal intraocular lens (IOL) after phacoemulsification and refractive lens exchange (RLE). Patients and Methods: In this prospective, multicenter clinical trial, 63 presbyopic subjects who had cataract or where RLE candidates were bilaterally implanted with the Precizon Presbyopia IOL (Ophtec BV, Groningen, the Netherlands) after phacoemulsification. The study was conducted at 6 clinical centers in Germany, the Netherlands, Belgium, Turkey and Spain. Subjects were evaluated at baseline and at 1 day, 1 week, 1 and 3 months postoperatively for monocular and binocular uncorrected (UDVA) and corrected distance visual acuity (CDVA), uncorrected (UIVA) and distance-corrected intermediate visual acuity (DCIVA), uncorrected (UNVA), corrected (CNVA) and distance-corrected near visual acuity (DCNVA), contrast sensitivity and quality of vision. Results: Three months postoperatively, binocular UDVA and CDVA of ≥20/40 was achieved in 98.4% (60/61) and 100%, respectively. Binocular UIVA and DCIVA of ≥20/40 was achieved in 96.7% (59/61) and 93.4% (57/61) respectively. Binocular UNVA, CNVA and DCNVA of ≥20/40 was achieved in 93.4% (57/61), 98.4% (60/61) and 95% (57/60) subjects, respectively. Complete spectacle independence was achieved in 80% (49/61) patients; 93% of patients reported that they were quite or very satisfied with the outcomes of the procedure. Conclusion: Precizon Presbyopia IOL implantation is a safe and effective method to provide good visual acuity at all distances in presbyopic and cataract patients.

To evaluate the visual outcomes and patient satisfaction after unilateral implantation or stepwise bilateral implantation of an apodized diftractive multifocal intraocular lens (IOL). Private practice, Cincinnati, Ohio, USA. Patients requiring cataract surgery in 1 eye were recruited. AcrySof ReSTOR IOLs were implanted in 1 eye of patients with phakic contralateral eyes, patients with contralateral monofocal IOLs, and patients with a contralateral multifocal IOL of the same model. Six months postoperatively, patients were assessed for visual acuity (31.0 cm, 50.0 cm, 4.0 m), contrast sensitivity, and stereopsis. Patients were surveyed for visual disturbances and lifestyle visual quality. Of unilateral multifocal IOL patients, 75% were satisfied with their vision (score 7.3 out of 10) and a majority (56% multifocal-phakic, 65% multifocal-monofocal) achieved spectacle independence. These values were slightly lower than values for bilateral multifocal patients (92% satisfied, 77% spectacle independent), but not at a statistically significant level. Mean overall patient satisfaction was statistically significantly different: 8.9 for bilateral patients versus 7.3 for unilateral patients. Objectively, significant differences favored bilateral implantation over unilateral implantation for stereopsis, uncorrected near visual acuity, and best corrected near and intermediate visual acuities. Contrast sensitivity was similar between groups in most cases. The incidence of halos was lower in unilateral patients (57%) than in bilateral patients (77%), although the difference did not reach statistical significance. Although unilateral implantation of a multifocal IOL provided patients with high levels of spectacle freedom and good visual acuity without compromising contrast sensitivity, overall clinical results favored bilateral implantation.
