“…The increased incidence of post-operative dysphotopsia associated with acrylic lenses with flattened edges was verified in Tester et al study comparing AcrySof® MA30 and MA60 with Silicone SI-40 IOLs and phakic controls 16. A non-comparative study of a single-piece hydrophilic acrylic IOL, the C-flex® IOL (Rayner Intraocular Lenses Limited, Hove, UK) demonstrated that although the rate of glare was similar to other types of IOL reported in Tester's study, the incidence of unwanted imagery was significantly less [15].…”

“…The Aspheric Balanced Curve (ABC) design provides a sharp visual image while the square edge of the lens helps to minimize posterior capsule opacification. However, hydrophobic acrylic IOLs have been shown to be associated with a higher rate of dysphotopsias than hydrophilic IOLs [15]. Therefore, we wanted to study both the rates of YAG capsulotomy and dysphotopsias following implantation of this IOL.…”

Purpose: to evaluate dysphotopsias, patient satisfaction and posterior capsulotomy rate in patients undergoing phacoemulsification and implantation with Hoya iSert 250 monofocal intraocular lens (IOL). Design: retrospective cohort study. Setting- Teaching unit at a District General Hospital, UK. Methods: patients were implanted with the hydrophobic acrylic Hoya iSert 250 monofocal IOL through a 2.2mm clear corneal/ limbal incision. For dysphotopsia data, patients responded to a telephone questionnaire describing any visual symptoms and their satisfaction. Nd:YAG laser capsulotomy data were collected retrospectively from electronic medical records, paper notes and laser records. Eyes from patients (mean age 73.6 range 64-93 years) undergoing cataract surgery with implantation of Hoya iSert 250 IOL during the period January 1, 2014 and July 31, 2014, and 2-year follow-up were analysed. Main outcome measures: dysphotopsia rate, patient satisfaction and posterior capsulotomy rate. Results: 106 patients had the Hoya iSert 250 lenses implanted over a seven month period in 2014. 88 patients were contacted at 24 months post- operatively. 18 had passed away or were not contactable. 61 patients completed the survey. 15 patients (24.5%) reported transient positive dysphotopsias. One patient (1.6%) reported negative dysphotopsia. 95% were either very satisfied or satisfied with their vision (59% 'very satisfied' and 36% 'satisfied'). 3 patients (4.9%) had a YAG laser capsulotomy within 24 months post-operatively. Conclusions: the Hoya iSert 250 monofocal IOL was associated with low dysphotopsia and posterior capsulotomy rates with the majority of patients being 'Very Satisfied' with their vision at 24 months. Posterior capsulotomy rate and dysphotopsias following implantation of Hoya iSert 250 monofocal intraocular lens: 24 month study.

“…A score is given to each answer, and a higher score indicates poorer QOL. We also asked questions regarding patient experience of unwanted images, satisfaction with vision, and disappointment due to unwanted images [ 11 , 12 ]. Finally, we recorded any side effects or complications over this 6-month period.…”

Comparison of Post-Cataract Surgery Visual Outcomes and Quality of Life in Patients Bilaterally Implanted with Multifocal Intraocular Lenses

Introduction: The present study compared visual outcomes in eyes with bilateral implantation of two multifocal intraocular lenses (MFIOLs)-the Eyecryl TM ACTV diffractive multifocal IOL (group 1) and AcrySof Ò IQ ReSTOR Ò multifocal IOL (group 2). Methods: This was a prospective, two-group observational longitudinal study of 118 eyes from 59 patients conducted at Laxmi Eye Institute, Panvel, India. We evaluated the patients at 1, 3, and 6 months. We assessed visual acuity, contrast sensitivity, higher-order aberrations, reading speed, defocus curve, stereopsis, quality of life (QOL), and adverse events in these participants. Results: The median (interquartile range) bestcorrected distance visual acuity was 0.18 (0, 0.18) in group 1 and 0.18 (0, 0.18) in group 2 at 1, 3, and 6 months; the difference was not statistically significant (p = 0.48). The binocular defocus curve in both groups showed two peaks at 0.0 to-0.5 D and at-2.5 D. The mean (95% confidence interval) critical print size was significantly different between groups 1 and 2 at low illumination (0.918 [0.905, 0.931] vs 1.154 [1.128, 1.180]; p = 0.004). Contrast sensitivity was significantly better in group 1 under mesopic conditions but not under scotopic conditions. Though total QOL did not differ significantly between groups, the psychosocial quality of life was significantly better in group 1. About 23% of patients in group 2 reported unwanted images, compared with 0% in group 1 (p = 0.01). Conclusion: We found that the Eyecryl and AcrySof groups were comparable for best-corrected visual acuity, photopic contrast sensitivity, defocus curve, reading parameters, stereopsis, and quality of vision. However, the Eyecryl group had better mesopic contrast and a lower proportion of unwanted images. Psychosocial quality of life was significantly better in the Eyecryl group; however, satisfaction was similar between groups. The cost of one of the lenses is less than the other. Thus, individuals with limited resources may opt for the Eyecryl TM ACTV, with similar visual outcomes.

Pseudophakic dysphotopsia are becoming increasingly important as unwanted side effect after cataract surgery. Objective: The purpose of this study is to compare the photic symptoms experienced by patients after cataract surgery. Material and method: This is a prospective study that included 105 eyes from 99 patients, which underwent uncomplicated phacoemulsification and IOL implantation, between June 2015 and June 2016, performed at Ophthalmology Clinic Tg Mureș. Patients without visually consequential ocular co-morbidity completed a questionnaire, designed to assess subjectively perceived visual functioning and identify symptoms of dysphotopsia. Results: From the total number of patient, hydrophobic lenses were implanted in 95 patients and 10 patients received hydrophilic lenses. Photic effects were reported in 18% of treated eyes. Although the percentage of dysphotopsia is higher in the hydrophobic lenses category, there was no significant statistical difference between the two categories. Conclusion: The incidence and significance should not be overlooked, thus visual acuity is not enough for evaluating postoperative visual function.
