The use of autologous serum for the treatment of patients with recurrent corneal erosion is effective and safe in reducing the number of recurrences experienced by patients.

Purpose To evaluate visual performance in relation to time after implantation of the multifocal Tecnis intraocular lens (IOL) in patients with cataract. Methods This prospective case series involved 250 eyes of 137 patients with cataract aged 68.5±9.9 years. Monocular uncorrected and corrected near visual acuity (NVA and DCNVA) and distance visual acuity (UCVA and BCVA), occurrence of visual symptoms, and patient satisfaction were evaluated at 1–3 days, 30–90 days, and 150–210 days after surgery. Posterior capsule opacification and contrast sensitivity under photopic conditions were also assessed. Results At the last follow-up visit, mean NVA and DCNVA was 0.215±0.082 and 0.189±0.045 log-MAR, respectively. The majority of eyes (96.8%) could read J2 without correction, including 83.2% reading J1. With best distance correction, 95.6% of eyes were able to read J1. Mean UCVA and BCVA was 0.144±0.101 and 0.09±0.03 logMAR, including 77.6% and 98.4% of eyes that achieved 20/30 or better, respectively. The majority of patients (>90%) ranked their near, distance, and global vision as good or excellent and 88.4% were free from spectacles. A significant improvement of uncorrected and corrected distance and near VA as well as a decrease in the intensity of subjective photic phenomena was observed over time. At the last follow-up visit, the rate of posterior capsule opacification (grade 1) was 4.4% and mean monocular contrast sensitivity was 1.44±0.26. Conclusions The multifocal Tecnis IOL provides excellent near vision and good distance vision in patients with cataract. However, most patients required a neuroadaptation period of approximately 6 months to experience full visual benefits of the lens. (Eur J Ophthalmol 2009; 19: 762–8)

Purpose: To evaluate the refractive and functional outcomes of the trifocal 1stQ AddOn ® (Medicontur) supplementary intraocular lenses (IOLs) designed for implantation into the ciliary sulcus. Patients and Methods: The study included 18 eyes of 11 pseudophakic patients with uncomplicated previous implantation of monofocal capsular bag IOLs. These patients had a desire for spectacle independence. Distance, intermediate and near visual acuities were measured, and defocus curves were plotted over a period of 6 months following implantation of the add-on IOLs. Intraocular pressure (IOP), endothelial cell density measurements and biomicroscopic evaluation were also performed. Results: In this study, 83.3% of eyes had spherical refractions within ±0.5 D from emetropia and 100% of eyes had spherical equivalent refractions that were within ±1.0 D of the target refraction. Visual acuities and defocus curves clearly confirmed trifocal optical performance (UDVA=0.03 ±0.05; UIVA=0.21 ±0.04; UNVA=0.12 ±0.04 logMAR; expressed as mean ±SD). Depth of focus showed identical results (DOF=0.486 D) compared to a trifocal capsular bag IOL, while the defocus curve was found to be superior in the intermediate and near ranges when compared to a trifocal capsular bag IOL. All patients achieved spectacle independence at all distances. All add-on IOLs were well positioned in the ciliary sulcus. No negative changes were noted in connection with endothelial cell counts, IOPs, the angle structure during surgery and during the follow-up period. Conclusion: The supplementary trifocal add-on IOL seems to be a safe, efficient and stable solution for achieving spectacle independence in pseudophakic patients with monofocal primary IOLs.

PurposeTo evaluate the development of visual acuity, dysphotopsia phenomena, and subjective sensations in patients implanted with the Tecnis® ZMB00 (Advanced Medical Optics Inc, Santa Ana, CA) multifocal intraocular lens.MethodsIn a sample of 70 eyes, distance and near visual acuity, with and without correction, contrast sensitivity, and patient satisfaction, were analyzed at 15, 30, and 60 days post-surgery.ResultsMean uncorrected distance visual acuity (logarithm of minimum angle of resolution) at 15, 30, and 60 days was 0.194 ± 0.054, 0.119 ± 0.026, and 0.076 ± 0.014 (P < 0.0001), respectively, and with correction, 0.051 ± 0.007 vs 0.041 ± 0.004 vs 0.022 ± 0.002 (P < 0.0001), respectively. At 60 days, 94.3% of eyes could read 1.00 close-up without correction. Patient satisfaction in terms of dysphotopsia effects and visual acuity was excellent. The mean contrast sensitivity was 1.64 ± 0.10 (logarithmic units) measured with the Pelli–Robson test.ConclusionThis type of multifocal intraocular lens was very effective at the distances analyzed, producing excellent objective and subjective results.
