Objective. To compare patient’s satisfaction level in performing routine activities during daylight and night vision after implantation with rigid, foldable, or rollable posterior chamber intraocular lens implants in uneventful cataract surgery. Design. Retrospective, cross-sectional. Place and Duration of Study. PNS SHIFA Hospital, Karachi, from Nov. 2009 to Nov. 2010. Methodology. 91 cataract surgery patients who had uneventful phacoemulsification, within the bag placement of intraocular lens and achieved best corrected visual acuity 6/9 or better were included in the study. Patients who developed postoperative complications were excluded. A specially designed questionnaire was used to assess patient’s satisfaction level of vision for those who underwent cataract surgery at least 3 months ago. Finally, they were categorized into five groups ranging from “very good” to “very poor.” SPSS version 16 was used to analyze the results. Results. There was a difference in satisfaction level between three groups. Vision was good in the day and the night with foldable posterior chamber intraocular lens implants. Conclusion. It was concluded that visual satisfaction level of patients who had foldable posterior chamber intraocular lens implantation was better during the day and night as compared to patients who had rigid or rollable posterior chamber intraocular lenses implantation.

Introduction: Piggyback IntraOcular Lenses (IOLs), or supplementary secondary implant lenses, have been developed to provide a sufficient dioptric power in eyes with high refractive defects, which are not fully correctable after cataract surgery with single IOL in the range of powers available. These lenses can also be used for the correction of refractive errors that occurred for a wrong choice of the IOL power after cataract surgery. Case description: We report the case of a complete refractive success obtained in a patient with an abnormal cornea, with a central stable ectasia, with thinning, high myopic astigmatism and cataract, obtained with the implant of a primary posterior chamber IOL at the time of cataract surgery and a subsequent implant of a secondary piggyback, sulcus-based customized toric IOL (Camellens FIL 622-2 Toric Monofocal IOL, Soleko, Rome, Italy). Conclusions: This brief report demonstrates the utility of combining primary and piggyback IOLs implant for the correction of a complex spherical-cylindrical refractive defect in a case of abnormal cornea and cataract.

Purpose: The aim of this article is to describe the safety and efficacy of trans-iris suture fixation for the management of late dislocation of in-the-capsular-bag intraocular lenses following uncomplicated cataract surgery. Patients and methods: Eleven eyes of 11 patients with late in-the-capsular-bag intraocular lens dislocation following uneventful phacoemulsification cataract surgery were recruited in the study. The dislocated intraocular lens–capsular bag complex was sutured to the iris at two points 180° apart using 9-0 polypropylene sutures on long needles. Results: Mean patient age was 67 ± 6 years. Seven eyes had pseudoexfoliation syndrome, one eye had Marfan syndrome, and another eye had a traumatic cataract; no risk factor was identified for intraocular lens dislocation in two eyes. A capsular tension ring had been implanted during cataract surgery in four eyes. In six eyes, the posterior chamber intraocular lenses were one-piece foldable while the remaining were three-piece intraocular lenses. Compared to the preoperative value, corrected distance visual acuity was significantly improved postoperatively ( p < 0.005). Intraoperative hyphema occurred in two eyes. Pupil ovalization was observed in all eyes. Mean endothelial cell count decreased by 4 ± 1.7% after intraocular lens fixation. The capsular bag–intraocular lens complex was stable and well-centered in the pupillary area in all eyes at the final follow-up examination which was performed 16 ± 4 months postoperatively. Conclusion: Trans-iris fixation is a simple and effective procedure for management of late intraocular lenses–capsular bag complex dislocation, without major complications.

Background:Four premature babies (eight eyes) undergoing simultaneous bilateral cataract surgery are presented and discussed.Methods:All four babies underwent simultaneous bilateral cataract surgery. Three babies (six eyes) had primary implantation of posterior chamber intraocular lenses (IOLs) and one baby (two eyes) had primary lensectomies with secondary visual correction with contact lenses. Results: In all eight eyes, there was no endophthalmitis and no spontaneous choroidal hemorrhages. All eyes experienced large myopic shifts, as high as –15.00 D. All six eyes with IOLs required secondary membranectomies, which did not reoccur. Case 4 had Lowe’s syndrome, was bilaterally aphakic post-op, and subsequently developed glaucoma requiring bilateral glaucoma surgery. Conclusions: Simultaneous bilateral cataract surgery in severely premature babies can be successful in restoring vision over the long term. Strategies to successfully deal with the timing of surgery, IOLs, secondary membranes, secondary glaucoma, appropriate IOL powers, and IOL formulas is discussed. Successful long-term successful visual outcomes are now possible in this complex group of premature babies.

Purpose Subluxated or malpositioned intraocular lenses (IOLs) and inadequate capsular support is a challenge for every ophthalmic surgeon. Iris suture of an IOL seems to be an easy technique for the management of dislocated 3-piece IOL, allowing the IOL to be placed behind the iris, far from the trabecular meshwork and corneal endothelium. The purpose of this study is to assess the results of pars plana vitrectomy (PPV) and iris suture of dislocated 3-piece acrylic IOLs. Methods In this retrospective, nonrandomized, interventional case consecutive study, of a total of 103 dislocated IOLs, 36 eyes were considered for analysis. All 36 eyes had subluxated or totally luxated 3-piece IOL and underwent iris suture at the Ophthalmology Department of Santa Maria Hospital-North Lisbon Hospital Center, Portugal, from January 2011 until November 2015. All patients underwent 3-port 23-G PPV. The optic zone of the dislocated IOL was placed anterior to the iris with the haptics behind, in the posterior chamber. Haptics were sutured to iris followed by placement of the optics behind iris plane. Postoperative measures included best-corrected visual acuity (BCVA), IOL position, intraocular pressure, pigment dispersion, clinical signs of endothelial cell loss, and development of macular edema. Results A total of 36 eyes of 36 patients were included. All underwent successful iris fixation of dislocated 3-piece IOL. Mean overall follow-up was 15.9 months (range 3-58 months). At presentation, 16 eyes (44.4%) had a luxated IOL and 20 eyes (55.6%) a subluxated IOL. As underlying cause, 17 eyes (47.2%) had a history of complicated cataract surgery, 5 eyes (13.9%) had a traumatic dislocation of the IOL, and 6 eyes (16.7%) had a previous vitreoretinal surgery. A total of 8 eyes (22.2%) had late spontaneous IOL dislocation after uneventful cataract surgery. The mean preoperative BCVA was 1.09 ± 0.70 logarithm of the minimal angle of resolution (logMAR) units and mean postoperative BCVA was 0.48 ± 0.58 of logMAR units. The mean visual acuity improvement was 4.08 ± 5.33 lines on the logMAR scale. In this study, every IOL was stable at the last follow-up. As late complications, macular edema occurred in 1 patient and retinal detachment occurred in 2 patients. There were no cases of endophthalmitis. Conclusions Iris suture fixation of subluxated IOL is a good treatment option for eyes with dislocated IOLs, leading to long-term stability of the IOL. The advantage of this procedure is using the same IOL in a closed eye surgery. No astigmatic difference is expected as no large corneal incision is needed.

We report the surgical management of a patient with bilateral anterior lenticonus due to Alport syndrome using femtosecond laser-assisted cataract surgery (FLACS) and the Optiwave Refractive Analysis (ORA) system. A 38-year-old man with Alport syndrome presented to our department with visual loss due to anterior lenticonus in both eyes. Adjustments during bilateral FLACS were performed with the software’s calipers to manually delineate the anterior capsulotomy. Multifocal toric intraocular lenses (IOLs) were selected and placed in the posterior chamber with the aid of intraoperative aberrometry. The intended postoperative positioning parameters for the IOL as well as the planned visual acuity and refraction were achieved. The implementation of FLACS and intraoperative wavefront aberrometry is a safe and useful surgical approach for the management of cataract in challenging cases such as patients with anterior lenticonus due to Alport syndrome.

Best Corrected Visual Acuity

Currently, posterior chamber intraocular lenses (IOLs) correct totally or partially spherical aberrations. In this article we present the visual results of a prospective multicentre study evaluating the Micro AY IOL correcting 0.11μm of spherical aberration, which is a good compromise between optimal vision and a consistent depth of focus. We evaluated 124 eyes that were operated on using bi-manual micro-cataract surgery (BiMICS: 75%) or co-axial micro-cataract surgery (CoMICS: 25%) phacoemulsification with insertion of a Micro AY IOL through a 1.8–2.2mm incision. Mean post-operative best corrected visual acuity was 0.97±0.25; pre-operative spherical aberrations were +0.24±0.13μm, and reached +0.10±0.11μm post-operatively. There were no complications due to the lens, and photopic contrast sensitivity reached high levels.
