Aim: To evaluate the effect of phacoemulsification with intraocular lens implantation in eyes with pre-existing trabeculectomy.Methods: This prospective single-center clinical study evaluated intraocular pressure in 60 eyes of 60 patients who underwent phacoemulsification and implantation of a foldable intraocular lens after a previous successful trabeculectomy. Patients who had a trabeculectomy more than one year prior to the study were included. Intraocular pressure, number of antiglaucoma medications, bleb appearance, and visual acuity were recorded preoperatively, and at each follow-up examination and 12 months after phacoemulsification.Results: The mean intraocular pressure before phacoemulsification was 12.42 mmHg (SD, 4.60 mmHg), which increased to 14.98 mmHg (SD, 4.18 mmHg), 14.47 mmHg (SD, 3.58 mmHg), 15.44 mmHg (SD, 3.60 mmHg), and 15.71 mmHg (SD, 3.47 mmHg) after one, three, six, and 12 months, respectively. At each follow-up visit, the mean IOP was significantly higher than the preoperative value (p < 0.001, p = 0.015, p ≤ 0.001, and p = 0.001 at month one, three, six, and 12, respectively). The mean preoperative best-corrected visual acuity was 0.98 logMAR (SD, 0.44 logMAR) and the mean postoperative best-corrected visual acuity at 12 months was 0.20 logMAR (SD, 0.21 logMAR) [p = 0.0001]. The mean preoperative number of antiglaucoma medications used was 0.57 (SD, 0.63), which increased to 0.65 (SD, 0.63 ), 0.70 (SD, 0.72 ) 0.68, (SD, 0.70), and 0.67 (SD, 0.77 ) at one, three, six, and 12 months, respectively, but there were no statistically significant differences. Bleb size decreased clinically after phacoemulsification. Nineteen of 60 eyes (32%) developed fibrosis of bleb with decreased bleb size.Conclusion: Phacoemulsification with intraocular lens implantation significantly increased intraocular pressure and increased the number of antiglaucoma medications in eyes with pre-existing functioning filtering blebs.

Abstract: Introduction and aim: The correction of aphakia might be a challenge for the surgeon. The aim of this study is to describe the authors’ experience with the implantation of the retropupillary iris clip intraocular lens. Method: Patients between January 2014 and December 2015 were included in the retrospective study. Retropupillary implantation of iris clip intraocular lens VRSA 54 (AMO Advanced Medical Optics, USA) was performed in all cases. The minimum follow up period was three months. The stability of the intraocular lens and the intraoperative and postoperative complications and the visual acuity were evaluated. Results: During this time period 11 cases (1 female, 10 males) were included in the study. The mean age at the time of the implantation was 57.7 years (between 25–74 years). In 4 cases the iris clip lens was implanted during the first intervention, in 7 cases during the secondary procedure. In all cases the lens was fixated onto the iris posteriorly. The best corrected visual acuity before the iris clip implantation was 0.43 (0.1–1.0) and postoperatively at the time of the follow up 0.49 (0.04–1.0). Conclusions: With the use of the retropupillary implanted iris clip intraocular lens all of the patients could have been rehabilitated without major complications. Orv. Hetil., 2017, 158(1), 20–24.

Aim: To evaluate the retinal light scattering, visual acuity, refraction and subjective satisfaction in patients after implantation of Acrysof IQ PanOptix intraocular lens. Methods: Our group included 32 eyes of 21 patients who underwent cataract surgery or refractive lensectomy with Acrysof IQ PanOptix multifocal intraocular lens implantation at the Ophthalmology Clinic of Faculty Hospital Hradec Králové during the time from September 2015 to December 2017. The observed parameters were visual acuity, subjective refraction, retinal light scattering and patient‘ subjective satisfaction. Preoperative refractive values and visual acuity values were compared with results obtained on day 1, 1 month and at an average of 27 months postoperatively. Subjective satisfaction and degree of light scattering on the retina were evaluated at the end of the follow-up period. Results: Preoperative, uncorrected distant visual acuity improved from an average of 0,51 ± 0,29 (expressed in decimal values) to 0,94 ± 0,10 at the end of the follow-up period. Preoperative best-corrected distance visual acuity improved from an average of 0,95 ± 0,19 to 1,00 ± 0,09 at the end of the follow-up period. The mean value of preoperative uncorrected near visual acuity was 8,29 ± 4,93 of Jaeger charts, the mean value of uncorrected near visual acuity at the end of the follow-up period was 1,00 ± 0 of Jaeger charts. Subjective satisfaction was assessed using a standardized VF-14 questionnaire at least 1 year after surgery (mean follow-up of 27 months). Retinal light scattering was examined using an Oculus C-Quant instrument. The retinal light scattering value in our sample was 1,12 ± 0,19. In only 6 eyes of 4 patients, the resulting value was outside the physiological range used for eyes with lens crystallina Conclusion: The value of light scattering on the retina is a factor affecting the degree of sensitivity to glare after implantation of multifocal intraocular lenses. In our group, we observed a deviation from the physiological range of retinal light scattering in only 6 eyes of 4 patients, but this did not lead to a deterioration in subjective postoperative satisfaction.

Aim. The objective of the present study was to analyze the results of the surgical treatment of the children presenting with posterior lenticonus associated with congenital cataract. Materials and methods. The total of 8 children (8 eyes) with posterior lenticonus enrolled in this study accounted for 6.5% of all cases of congenital cataract treated at the “Excimer” Eye Center during the period from 2003 to 2015. The age of the patients varied from 0.2 to 15 (mean 8.1±3.8) years. Preoperatively, the uncorrected visual acuity was estimated to be 0.11±0.1 (0.01 - 0.3), with the best corrected visual acuity being 0.15±0.13 (range: 0.01 - 0.4). Lensectomy was performed under general anesthesia by means of the incision technology (1.8 and 2.2 mm) with the use of the Millenium, Stellaris microsurgical system (Bausch and Lomb, USA) and the Infinity system (Alcon, USA). In all the cases, different IOL models (Alcon, USA) were implanted; in four cases, the toric intraocular lenses were used. Results. In all the patients with posterior lenticonus and congenital cataract, the “dry” aspiration of the lens was performed. The distinctive features of posterior capsulorhexis included the use of two viscoelastic materials, viz. heavy Healon GV applied over the intraocular lens and ProVisc applied under the intraocular lens in the form of a “layer cake”. Thereafter, posterior capsulorhexis and vitrectomy were done. The lens was implanted into the capsular bag (n = 6) and into the ciliary sulcus (n = 2) with the anterior and posterior “optic capture”; the edges of the optical hole were placed behind the capsulorhexis hole. In the cases of the initial posterior capsular defect (n = 3), we performed vitreorhexis and vitrectomy followed by intraocular lens implantation. The best corrected visual acuity increased from 0.15 before the operation to 0.72 after surgery, with astigmatism being reduced from 2.3±0.9 to 1.6±065 diopters (overall astigmatism for the entire group) and from 1.81±0.46 to 0.56±0.56 diopters for the subgroup treated by means of toric IOL implantation. The patients remained under the observation during the follow-up period of more than 36 months. Conclusion. Lensectomy followed by intraocular lens implantation used for the treatment of the children presenting with posterior lenticonus and congenital cataract is the efficient method for the management of this combined pathology. Such features of the surgical technique as “dry” aspiration of the lens mass, posterior capsulorhexis, anterior vitrectomy, and optical capture taken together make it possible to achieve the favourable and stable functional outcome of the treatment.

Purpose: To describe the outcome of phacoaspiration with intraocular lens implantation in children with unilateral congenital cataract in the first 4 years of life. Methods: A retrospective chart review of children with visually significant unilateral congenital cataract presenting in the first 4 years of life was done. Children with a minimum postsurgical follow-up of 1 year were included. Outcome measures were mean spherical equivalent, visual axis clarity, visual acuity and complications till the last follow-up. Results: Ninety-three children met the inclusion criteria. The mean age of surgery was 13.23 ± 11.89 months and the mean follow-up period was 24.37 ± 17.35 months. Nearly 40% of children presented during their first year of life. No difference was noted between the subgroups in terms of age ( p = 0.310), sex ( p = 0.475) or laterality ( p = 0.349). Surgical membranectomy was performed in 22 eyes (23.6%) after an average period of 4.85 ± 2.58 months after surgery. One eye underwent piggy back intraocular lens and four eyes underwent intraocular lens exchange after a mean duration of 50 months (range 40–60 months). The mean visual acuity was 0.79 ± 0.11 (log MAR chart). A total of 60.7% of these children ( n = 31) achieved best corrected visual acuity or 20/80 or better. Conclusion: The results of our study suggest that primary intraocular lens implantation in children with unilateral congenital cataract gives good structural and functional results. Besides a meticulous surgery, visual outcome is affected by the time of presentation and postoperative compliance to amblyopia therapy.

Introduction: Intraocular lenses have always been a controversial topic in pediatric cataract surgery. In the early 1990s in the post-Soviet states of Eastern Europe, intraocular lenses promised an easier full-time correction and amblyopia treatment. Since 1991, ophthalmologists in Latvia have been implanting intraocular lenses in infants. Amount of the postoperative myopic shift and its influencing factors, analyzed in this article, are important indicators of congenital cataract treatment. Materials and methods: A retrospective chart review off 85 children (137 eyes) who underwent foldable posterior chamber intraocular lens implantation at the Clinical University Hospital in Riga, Latvia, from 1 January 2006 until 31 December 2016, was performed. Depending on the age at surgery, patients were divided into six groups: 1–6, 7–12, 13–24, 25–48, 49–84, and 85–216 months. Results: The largest and more variable myopic shift was found in a group of diffuse/total and nuclear cataract with surgery before the age of 6 months. There was a statistically significant correlation between the acquired best-corrected visual acuity and the amount of myopic shift (rs = 0.33; p < 0.001). Comparing the amount of myopic shift in two groups of different intraocular lens implantation target refraction tactics, we did not find statistically significant differences. Comparing the amount of myopic shift and implanted intraocular lens power, a negative, statistically significant correlation was found. Conclusion: The earlier the cataract extraction surgery and intraocular lens implantation is performed, the larger the myopic shift. The morphological type of cataract, best-corrected visual acuity, secondary glaucoma, and intraocular lens power influence the amount of myopic shift.

Abstract Purpose: To evaluate the efficacy of trabeculectomy with intraoperative subtenon injection of Mitomycin C (MMC) in terms of control of Intraocular pressure post-operatively.Study design: Observational studyMethods: A total of 49 patient’s medical records who underwent trabeculectomy with intraoperative subtenon injection of MMC with diagnosis of Primary Open Angle Glaucoma (POAG) from January 2017 to December 2018 were evaluated to see the post-operative outcomes in terms of control of intraocular pressure (IOP) with 12 months follow-up. The medical records were retrieved using the hospital information system. Age, gender, pre-operative IOP, Best-Corrected Visual Acuity (BCVA), co-morbids, previous surgery, Central Corneal Thickness (CCT), fundus findings, number of glaucoma medications and postoperative complications were obtained by using a proforma.Results: Total 72 eyes of 49 patient records were evaluated to see post operative outcomes at three, six and twelve months follow up. The mean IOP preoperatively was 24.68±13.66 mm Hg with maximum anti-glaucoma treatment. After the surgery the mean IOP was 13.69±6.68 mmHg at 3 months follow-up, and 12.68±4.04 and 13.33±4.8 mmHg at 6 and 12 months respectively (P-value 0.001). Preoperatively mean CCT was 529.81±28.75 and at 12 months follow-up after surgery was 530.45±29.43 with P-value 0.245. Best Corrected Visual Acuity outcomes were seen at each follow-up and results were found to be statistically significant (P value ≤ 0.05).Conclusions: Twelve months follow-up of trabeculectomy show that intraoperative subtenon injection of MMC is effective in terms of control of IOP postoperatively with minimal complications in patients with POAG.
