Visual function and complications after cataract surgery with bilateral multifocal intraocular lens implantation

PURPOSE: To evaluate the visual function and complications after cataract surgery with bilateral Array SA 40N multifocal intraocular lens (IOL) implantation. MATERIAL AND METHODS: This prospective study comprised 40 eyes of selected 20 patients undergoing cataract surgery with bilateral implantation of Array SA 40N (AMO). multifocal IOL. Three months after bilateral surgery distance and near visual acuity, contrast sensitivity, complications and adverse effects were evaluated. Patients' satisfaction was assessed using a subjective TyPE Questionnaire. RESULTS: Thirty-five eyes (35/40 - 87.5%) achieved the uncorrected distance visual acuity 20/40 and the uncorrected near visual acuity of J5 or better. Eighty-two and a half percent of the operated eyes achieved UCDVA 20/20 and J4 or better. Contrast sensitivity for distance and near measured binocularly were within normal limits, although for higher spatial frequency, contrast sensitivity values for near were slightly above the lower limit of normal range. Intraoperative and postoperative complications were few and only in one eye, further surgical intervention was necessary (IOL recentration). Three patients (3/20 - 15%) reported moderate glare and halo. Overall visual satisfaction measured with TyPE Questionnaire was very high (8.7/10). CONCLUSIONS: Bilateral multifocal IOL implantation was effective and safe in selected cataract patients, providing very good uncorrected distance and near visual acuity. Slightly reduced contrast sensitivity and increased perception of glare/halo were an acceptable compromise for near, as well as distance vision improvement.     

Decentration, tilt, and near vision of the array multifocal intraocular lens

PURPOSE: To study the periodic changes in decentration, tilt, and near vision in eyes with the Array(R) multifocal intraocular lens (IOL). SETTING: Department of Ophthalmology, St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Korea. METHOD: This study comprised 20 eyes of 10 patients older than 60 years who had binocular cataract and bilateral implantation of the Array multifocal IOL. Mean patient age was 66.0 years (range 60 to 75 years). After a clear corneal incision and continuous curvilinear capsulorhexis were made, each eye had phacoemulsification and in-the-bag IOL implantation. The amount of IOL decentration and degree of tilt were evaluated using the EAS-1000 anterior eye segment analysis system 1 day and 1 and 2 months postoperatively. Near and far visual acuities were measured at the same examinations. RESULTS: No statistically significant differences were observed in decentration (P =.13) or tilt (P =.32) throughout the follow-up. Mean uncorrected distance visual acuity was 0.68 +/- 0.27 (SD), and mean uncorrected near acuity was 0.49 +/- 0.15 2 months postoperatively. Uncorrected distance acuity better than 0.5 was achieved in 14 eyes (77.8%), in which the mean uncorrected distance acuity was 0.80 +/- 0.18 and the mean uncorrected near acuity was 0. 53 +/- 0.14 2 months postoperatively. CONCLUSIONS: Tilt and decentration of the Array multifocal IOL showed no significant progression up to 2 months after implantation. For near acuity, the Array IOL may be an effective aid.

Functional vision after cataract removal with multifocal and accommodating intraocular lens implantation: prospective comparative evaluation of Array multifocal and 1CU accommodating lenses

PURPOSE: To compare the efficacy (functional vision, spectacle dependence) of the Array multifocal intraocular lens (IOL) (Advanced Medical Optics) and the 1CU accommodating IOL (HumanOptics AG). SETTING: Hartswood Hospital, Brentwood, United Kingdom. METHODS: This prospective study comprised patients scheduled to have standard phacoemulsification surgery with IOL implantation. Patients expressing a preference for spectacle independence were allocated to the Array multifocal IOL group. Those expressing no preference received the 1CU accommodating IOL. Efficacy measures included distance and near uncorrected visual acuity (UCVA), dynamic retinoscopy, and patient-reported spectacle independence. RESULTS: Seventeen patients (34 eyes) had bilateral implantation of the Array multifocal IOL, and 5 patients (9 eyes) had implantation of the 1CU accommodating IOL. Six to 18 months after surgery, 82.4% of eyes in the multifocal IOL group and 77.8% in the accommodating IOL group achieved a distance UCVA of 20/20 (Snellen) or better; the difference between groups was not significant. However, a significantly greater proportion in the multifocal IOL group than in the accommodating IOL group (76.5% versus 44.4%) achieved a near UCVA of N5 (Snellen 20/40) or better (P=.0068). Sixteen patients (94.1%) with Array IOLs and 2 patients (50.0%) with 1CU IOLs reported spectacle independence. Dynamic retinoscopy showed that the mean accommodative effect in the 1CU group was 0.44 diopter. CONCLUSIONS: In this single-surgeon single-site study, a greater proportion of Array multifocal IOL recipients than 1CU IOL recipients achieved functional near visual acuity. Only 1 patient with an Array IOL required corrective spectacles at the last visit.     

Synchrony dual-optic accommodating intraocular lens. Part 2: pilot clinical evaluation

PURPOSE: To evaluate the clinical outcomes of an accommodating dual-optic intraocular lens (IOL). SETTING: Private practice and university centers. METHODS: A prospective noncomparative case series with retrospective control comprised 21 patients (26 eyes) scheduled for small-incision extracapsular cataract extraction by phacoemulsification with implantation of the Synchrony dual-optic accommodating IOL (Visiogen) (accommodating IOL group) and 10 patients who had small-incision extracapsular phacoemulsification with implantation of a monofocal, single-optic IOL at least 6 months previously (control group). Patients were examined 1, 3, 6, and 12 months after surgery. Defocus curves in the accommodating IOL group were compared with those in the control group. The main outcome measures were postoperative distance uncorrected and best corrected visual acuity; near uncorrected, distance corrected, and near corrected visual acuity; and accommodative range based on defocus curves. RESULTS: Twenty-four eyes were available at the 6-month follow-up visit. All eyes had best corrected distance visual acuity of 20/40 or better, and 19 eyes (79%) had an uncorrected distance visual acuity of 20/40 or better. Uncorrected near visual acuity was 20/40 or better in all eyes. With distance correction, 23 eyes (96%) had an acuity of 20/40 or better at near. Defocus curve analysis suggested a mean accommodative range of 3.22 diopters (D) +/- 0.88 (SD) (range 1.00 to 5.00 D) in the accommodating IOL group and 1.65 +/- 0.58 D in the control group (range 1.00 to 2.50 D) (P<.05). CONCLUSION: The Synchrony dual-optic IOL shows promise as an option to provide accommodative function in pseudophakic patients.     

Near vision restoration with refractive lens exchange and pseudoaccommodating and multifocal refractive and diffractive intraocular lenses: comparative clinical study

PURPOSE: To evaluate near visual performance after implantation of a pseudoaccommodating intraocular lens (IOL) (Crystalens AT-45, eyeonics) or a multifocal IOL (refractive model, AMO Array; diffractive model, AcriTec TwinSet) after lens surgery. SETTINGS: Instituto Oftalmologico de Alicante, Miguel Hernandez University, Alicante, Spain. METHODS: Forty patients were included in this prospective clinical comparative study. The patients were divided into 3 groups according to the type of IOL implanted. Group 1 included 24 eyes (12 patients) implanted with the Crystalens IOL; Group 2, 32 eyes (16 patients) with the Array IOL, and Group 3, 24 eyes (12 patients) with the TwinSet IOL. Bilateral phacoemulsification and IOL implantation were performed in all patients, and the follow-up was 1 year. The postoperative main visual outcome evaluations were uncorrected and best corrected distance and near visual acuities, mean add for near, and best distance-corrected near acuity. RESULTS: In Group 1, the mean uncorrected near acuity was 20/40 preoperatively and 20/25 after 1 year. The mean preoperative best distance-corrected near acuity was 20/32 and 20/25 after 1 year. In Group 2, the mean uncorrected near acuity was 20/40 and 20/25, respectively. The mean preoperative best distance-corrected near acuity was 20/32 and 20/25 after 1 year. In Group 3, the mean uncorrected near acuity was 20/63 preoperatively; after 1 year, it was approximately 20/25. The mean best distance-corrected near acuity was 20/50 and 20/25, respectively. A neodymium:YAG laser capsulotomy was performed for posterior capsule opacification when required, with no change in the refractive outcome. CONCLUSIONS: Implantation of multifocal and pseudoaccommodating IOLs provides adequate near vision restoration. The TwinSet IOL provided faster recovery of near vision than the other 2 IOLs. The Crystalens IOL provided less postoperative visual phenomena with favorable near vision. The Array IOL achieved the most comfortable distance and near vision.     

Refractive lens exchange with an array multifocal intraocular lens

PURPOSE: To prospectively evaluate safety, efficacy, predictability, stability, complications, and patient satisfaction after refractive lens exchange (clear lens extraction) followed by posterior chamber implantation of a multifocal intraocular lens (IOL). METHODS: Fifty eyes of 25 patients (mean age 51 years, range 44 to 62 years) with preoperative spherical equivalent refraction between -15.50 and +5.75 D and cylinder between 0 and 1.50 D underwent bilateral implantation of a zonal progressive multifocal IOL (Array, AMO). RESULTS: Eyes were divided into group A (n=24; myopia, average preoperative spherical equivalent refraction -7.11 +/- 3.25 D (-1.75 to -15.50 D), and group B (n=26; hyperopia, average preoperative spherical equivalent refraction +3.04 +/- 1.04 D). Follow-up was 6 months in all eyes. Postoperatively, all eyes of both groups were within +/-1.00 D of target refraction. No eye in group A and three eyes in group B sustained a loss of one line of BSCVA. Forty-seven eyes (94%) remained unchanged or gained one or more lines of their preoperative BSCVA. In all eyes, postoperative UCVA was 20/40 or better. When compared to preoperative, uncorrected near visual acuity improved (statistically significant). All patients achieved uncorrected binocular visual acuity of 20/30 and J4 or better. Patient satisfaction was extremely high; no intra- or postoperative complications were reported. CONCLUSION: Six-month results of implantation of the AMO Array multifocal IOL for refractive lens exchange demonstrated safety, efficacy, and predictability in correcting high ametropia and significant improvement of uncorrected near and distance visual acuity.     

Refractive outcomes after bilateral multifocal intraocular lens implantation

PURPOSE: To evaluate the efficacy and safety of bilateral multifocal intraocular lens (IOL) implantation after cataract surgery. SETTING: Oftalmológico de Valencia-CEOVAL, Valencia, Venezuela. METHODS: This retrospective study evaluated patient charts for the patient selection method, preoperative evaluation, surgical technique, postoperative visual and refractive outcomes, and complications. It included 70 eyes of 35 patients who had lens extraction with bilateral implantation of an Array multifocal IOL. Fourteen eyes of 7 patients had hyperopia with presbyopia, and 56 eyes of 28 patients had cataract. RESULTS: All eyes achieved an uncorrected distance acuity of 20/40 or better and an uncorrected near acuity of J5 or better. Six patients (18%) reported moderate halos, and 22 patients (63%) occasionally wore glasses. CONCLUSION: Bilateral multifocal IOL implantation was effective and safe in cataract and hyperopic patients with presbyopia, providing good uncorrected distance and near acuities.     

Outcomes of sulcus implantation of Array multifocal intraocular lenses in second-eye cataract surgery complicated by vitreous loss

PURPOSE: To evaluate the outcomes of implantation of the Array((R)) multifocal intraocular lens (IOL) (model SA-40N, AMO) in the ciliary sulcus in second-eye cataract surgery complicated by vitreous loss. SETTING: Department of Ophthalmology, Arrowe Park Hospital, Wirral, United Kingdom. METHODS: This retrospective study comprised 15 patients who had complicated second-eye cataract surgery with loss of posterior capsule support leading to sulcus implantation of an Array multifocal IOL. The patients were recalled for assessment. Objective evaluation included uncorrected and corrected distance and near visual acuities, complications, and IOL centration. Subjective assessment was performed using a questionnaire that included the VF-14 index of visual function; the questions were related to satisfaction with vision, limitations from halos and glare, and the frequency of spectacle wear. RESULTS: Fourteen eyes (93%) had postoperative visual improvement. The best corrected distance acuity was 6/12 or better in 11 eyes (73%). The best corrected near acuity was J2 or better in 12 eyes (80%). The IOL was well centered in 11 eyes (73%) and slightly decentered in 4 eyes (27%). Subjectively, patients indicated a high level of satisfaction with their distance and near vision. The VF-14 indicated high levels of visual function, with 73% of patients having a score higher than 90 (out of 100). Seventy-three percent of patients were not troubled by glare or halos, and 40% did not wear spectacles. CONCLUSION: Implantation of the Array multifocal IOL in the sulcus during complicated phacoemulsification led to good visual outcomes based on objective and subjective patient measures.
