Introduction: Cataract is an eye lens opacification which prevents clear vision. It is the leading cause of blindness and vision impairment worldwide, including Indonesia. It can also be occurred in children that leads to a major cause of childhood blindness. The prevalence of childhood cataract ranges from 3 to 6 per 10,000 children. The main treatment for cataract is surgery, although pediatric cataract surgery has several complications. One of the most severe complication is glaucoma due to increased intraocular pressure (IOP). This study aimed to determine pre- and post-operative IOP in pediatric cataract surgery.Methods: This was a cross-sectional observational analytic study. Secondary data were collected from medical records of Department of Ophthalmology, Dr. Soetomo General Hospital Surabaya from January 2017 to August 2019. Age, gender, pre- and post-operative IOP, and intraocular lens implantation data were taken. Calculation was performed using the Saphiro-Wilk for data less than 50 samples. The Saphiro-Wilk test results showed that the data were normally distributed (p = 0.628). Data processing were then performed using the parametric t-pair test with a confidence level ofResults: 32 eye samples were obtained from 16 pediatric cataract surgery patients. The mean of pre-operative IOP was 13.05 mmHg and the mean of post-operative IOP was 13.36 mmHg. There was an increase in post-operative IOP with an average increase of 0.31 mmHg. There was no significant difference between pre- and post-operative IOP of pediatric cataract surgery patients (p = 0.711).Conclusion: There was no difference between pre- and post-operative IOP of pediatric cataract surgery patients at Dr. Soetomo General Hospital Surabaya for the period of January 2017 - August 2019.

Purpose: To compare refractive outcome of posterior Optic Capture versus In-the-bag Implantation of Intraocular Lenses in Pediatric Cataract Surgery. Design: Prospective, randomized and comparative study. Methods: Forty eyes of 25 children (12 males and 13 females) were included in this study with unilateral or bilateral cataracts in the pediatric age during the period between October 2018 to July 2019. These children were diagnosed to have congenital or developmental cataracts. All children underwent cataract surgery and IOL implantation. In our study, all children were divided into two groups: group (A) included 22 eyes that underwent posterior capsulorhexis and anterior vitrectomy with IOL implantation entirely in the capsular bag and group (B) included 18 eyes that underwent posterior capsulorhexis and posterior optic capture of the IOL. Patient demographics, surgical intervention, presenting symptoms, postoperative refraction and follow up of refractive changes for 6 months were recorded. Results: Ten cases were unilateral and fifteen cases were bilateral. The mean age was 5.44 ±3.30 in group (A) while the mean age was 4.26±1.45 in group (B). At 1.5 month, the mean spherical error in group (A) was 2.85 ± 1.41 D  with range from 1 to 6.5D, and the mean spherical error in group (B) was 2.50 ± 1.70 D with range from -0.75 to 3.75 D with no statistically significant difference in both groups. The mean cylindrical error in group (A) was -0.96 ± 1.87 D with range from -3.5 to 2.25D and the mean cylindrical error in group (B) was -1.38 ± 1.79 D with range from -3 to 2D with no statistically significant difference in both groups. At 6 months, the mean spherical error in group (A) was 0.73 ±1.89 D  with range from -4.00 to 3.75D and the mean spherical error in group (B) was 0.00 ± 2.27 D with range from -3.50 to 2.7D with no statistically significant difference in both groups. The mean cylindrical error in group (A) was -1.21± 0.90 D with range from -2.75 to 1.25D and the mean cylindrical error in group (B) was -1.68 ±0.93 D with range from -3.00 to -0.75D with no statistically significant difference in both groups. Conclusion: There was no statistically significant difference between in-the-bag intraocular lens implantation and intraocular lens posterior optic capture in the term of post-operative refraction.  Posterior optic capture helped in preventing posterior capsule opacification (PCO) postoperatively in all cases.

Purpose. To determine and to analyze the outcome of pediatric cataract surgery. Methods. A retrospective chart review of individuals aged up to 10 years who underwent cataract surgery between January 1, 2004, and December 31, 2014, at the UniversityHospital Zurich, Switzerland. Results. 63 children (94 affected eyes) with bilateral (68/94) or unilateral (26/94) cataract were identified. Surgery was performed at a median age of 1.5 months (IQR: 1.3–2.6 months) for the aphakic group (45/94) and of 50.7 months (IQR: 38.0–78.4 months) for the IOL group (49/94). At the last follow-up visit (median 31.1 months, IQR: 18.4–50.2 months), visual acuity was better in bilateral than in unilateral cataract cases. Posterior capsular opacification (PCO) was diagnosed in 30.9% of eyes without a significant difference in the IOL and aphakic groups (p=0.12). Aphakic glaucoma was diagnosed in 12/45 eyes at a median of 6.8 months (IQR 2.1–13.3 months) after surgery. Microcornea (5/12) and anterior segment anomalies (8/12) were associated with glaucoma development (p<0.05). Conclusion. Laterality and timing of surgery influence the outcome of pediatric cataract surgery. PCO was the most frequent postoperative complication. Aphakic glaucoma is often associated with ocular developmental abnormalities and a poor visual outcome.

Objective: To evaluate the intraocular pressure variation before and after phacoemulsification through pneumatic tonometry in addition to correlating it with the age, gender, and preoperative intraocular pressure of the patients evaluated. Methods: This is a cross-sectional observational study. Inclusion criteria were older than 18 years, deep anterior chamber visualized by the slit lamp and estimation of open angle using the Van Herick technique, intraocular pressure less than 21 mmHg, without surgical complications, and without any ocular disease. The intraocular pressure was measured by the pneumatic tonometer. The intraocular pressure assessment was performed at the last consultation before phacoemulsification surgery and 30 days after. Results: A sample of 182 eyes was used. The mean age was 68.41 ± 10.84 years. Of the patient, 65% were females and 35% were males. The mean intraocular pressure in the preoperative period was 16.0 mmHg (±3.3 mmHg) and the mean intraocular pressure in the postoperative period was 13.44 mmHg (±3.31 mmHg). There was no correlation between intraocular pressure variations in both eyes (age-matched open angle) and age. There was a statistically significant correlation between the preoperative intraocular pressure value and the intraocular pressure changes in the postoperative period. In the comparison of the intraocular pressure variation between the genders, the female gender presented a statistically significant negative variation. Conclusion: We conclude that the cataract surgery is related to the reduction of intraocular pressure in the postoperative period and this reduction is more influenced by its preoperative value. Other studies of high epidemiological impact are needed, which may corroborate that the cataract surgery could directly influence intraocular pressure variation.

Aim. The aim of the study is to examine changes in the anthropometric and refractive parameters of the eyeball in children with congenital cataracts who have been implanted with various types of IOLs (toric or classic monofocal). Materials and methods. In this work, we retrospectively studied the medical history of 34 children (42 eyes) aged 4 to 15 years, who underwent phacoemulsification of congenital cataracts with implantation of various types of IOLs: toric and simple monofocal. Further, in these groups, by statistical methods, the dynamics of refraction in the first three years after the operation, the incidence of postoperative astigmatism, and its dynamics were assessed. We also assessed the rate of change in the anteroposterior axis of the eyeball, the dynamics of refraction in terms of the total spheroequivalent and maximum visual acuity in 3 years after the operation. Results. According to the results of the study, it was shown that toric IOLs significantly better stimulate the process of emmetropization of the eyeball, and also have a significant tendency to completely eliminate postoperative astigmatism, within 3 years after surgery. However, there were no significant differences in maximally corrected visual acuity between the 2 compared groups. There were also no data showing a significant difference in the more frequent development of myopia in the group receiving the toric IOL. Conclusion. The correct choice and calculation of the IOL remains one of the most difficult tasks in pediatric cataract surgery. New technologies are introduced annually and require constant testing. In this study, we have shown the possibility of using toric IOLs and their positive effects in pediatric cataract surgery and in the prevention and treatment of obscuration amblyopia. Key words: pediatric cataract, intraocular lenses, myopia, refraction, phacoemulsification, amblyopia.

Background: Posterior capsular opacification (PCO) is the most frequent complication of cataract surgery. The objective of this study was to determine the frequency of acute rise of intraocular pressure (IOP) following Neodymium-Yttrium Aluminum Garnet (Nd:Yag) laser posterior capsulotomy. Materials & Methods: This cross-sectional study was conducted in the Department of Ophthalmology, HMC, Peshawar, Pakistan, from July-December 2016. Sample size was 325 selected by consecutive sampling technique. Inclusion criteria were all patients having significant PCO after uneventful cataract surgery with intra ocular lens implant. Demographic variables were sex, age groups and age in years. Research variable was presence of acute rise of IOP following Yag laser capsulotomy. Pre-laser assessment included slit lamp examination and recording of IOP with Goldmann applanation tonometer by a single ophthalmologist. IOP was measured 3 hours after Nd: Yag laser capsulotomy. Rise in IOP was labeled when IOP was ≥5 mmhg from baseline. Mean ±SD was used to express quantitative variables like age. Categorical variables were analyzed as frequency and percentage. Goodness-of-fit was applied to compare the frequency of acute rise in IOP between sample and population. SPSS-20 was used for data entry and its analysis. Results: Out of 325 patients, 170(52.3%) were men and 155(47.7%) were women. The mean age of the sample was 44.92 ±23.843 years. A total of 107(32.9%) patients were 20-39 years old whereas 218(67.1%) were 40-70 years. IOP was raised in 61 (18.8%) patients while in 264(81.2%) patients it was not raised. The frequency of acute rise in IOP after Yag laser capsulotomy was significantly different in sample compared to population. Conclusion: Men were more than women, especially of old age. The frequency of acute rise in IOP after Yag laser capsulotomy was significantly different in sample compared to population.

Purpose: To evaluate the use of intraocular injection of triamcinolone acetonide in pediatric cataract surgery with or without intraocular lens implantation as a vitreous dye to ensure a complete anterior vitrectomy and evaluate its effect on postoperative ocular inflammation, infection, posterior capsule opacification, and intraocular pressure. Methods: Randomized controlled trial included children diagnosed with bilateral congenital cataract in both eyes. Their eyes were randomly assigned into two groups: group A underwent aspiration, posterior capsulotomy, and anterior vitrectomy with intraocular injection of triamcinolone acetonide, while group B underwent the same surgical procedure without intraocular injection of triamcinolone acetonide. Intraocular pressure, postoperative inflammation, infection, and posterior capsule opacification were followed up till 6 months. Results: The study comprised 44 eyes of 22 children. The mean age was 2.4 ± 2.1 years including 10 males and 12 females. The mean postoperative intraocular pressure was within normal range in both groups. No case of infection in both groups. No eyes in group A showed reaction, while in group B, three eyes showed exudate on the first day, which improved at 2 weeks. Posterior synechiae was recorded in four eyes in group A and in five eyes in group B. Posterior capsule opacification was noted in one eye in group A at 3 month, while it was noted in nine eyes in group B. The difference was statistically significant ( p = 0.004). Conclusion: Triamcinolone acetonide was found to be useful in better visualization of vitreous in pediatric cataract surgery and has good effect in decreasing postoperative inflammation and posterior capsule opacification.

Purpose. The aim of this retrospective cohort study was to evaluate intraocular pressure (IOP) changes during femtosecond laser-assisted cataract surgery (FLACS) using two different patient interface systems. Methods. 116 eyes of 116 patients scheduled for cataract surgery were divided into 2 groups: group 1 (61 eyes) and group 2 (55 eyes) underwent FLACS using Catalys Laser with fluid interface (liquid optics interface, LOI) and LenSx Laser with curved interface and soft contact lens (SoftFit), respectively. IOP was assessed using a portable rebound tonometer (Icare®) preoperatively, after docking, immediately after surgery, at one and seven days postoperatively. Results. In group 1, the mean IOP (±SD) was 14.1 ± 0.4 mmHg before surgery, 33.2 ± 1.1 mmHg after docking, and 21.4 ± 0.9 mmHg immediately after surgery. In group 2, the mean IOP was 13.8 ± 0.4 mmHg before surgery, 24.2 ± 1.4 mmHg after docking, and 20.2 ± 1.2 mmHg immediately after surgery. After the docking procedure, a statistically significant increase in IOP from the baseline was found in both groups (p<0.001). Moreover, no statistically significant difference in IOP measured at 1 and 7 days postoperatively was observed compared with the preoperative values (p>0.05) using both laser platforms. No intraoperative and postoperative complications were observed. Conclusions. FLACS suction phase resulted in a transient increase of IOP in both groups, especially with the LOI system, and it is probably related to the greater pressure of a suction ring and suction generated through the vacuum, independently from the effect of femtosecond laser itself.

Introduction: The Bhaktapur Glaucoma Study is a population-based, cross-sectional and longitudinal study undertaken in one of the districts of Nepal. Objectives: To determine the prevalence of glaucoma in Bhaktapur district, Nepal. Materials and methods: Thirty clusters were randomly selected and a door-to-door census was conducted to identify citizens 40 years of age and older. Four thousand eight hundred individuals fulfilling the eligibility criteria were referred to the base hospital in Kathmandu for a detailed clinical examination. The diagnosis of glaucoma was based upon criteria described by the International Society for Geographic and Epidemiological Ophthalmology (ISGEO). Results: Complete data was available on 3991 subjects (response rate 83.15 %). The mean IOP was 13.3 mm Hg (97.5th and 99.5th percentiles, 18 and 20 mm Hg, respectively) and mean VCDR 0.26 (97.5th and 99.5th percentiles, 0.6 and 0.8 mm Hg, respectively). Seventy-five subjects had glaucoma, an age-sex-standardized prevalence of 1.80 (95 % confidence interval (CI), 1.68 - 1.92). The age-and sex-standardized prevalence of POAG was 1.24 % (CI, 1.14 - 1.34), PACG 0.39 % (CI, 0.34 - 0.45) and secondary glaucoma 0.15 % (CI, 0.07-0.36). The prevalence of glaucoma increased with increase in age and there was no significant difference in gender. Nine eyes were blind and two subjects bilaterally blind from glaucoma. Conclusion: The overall prevalence of glaucoma was 1.9 %. POAG was the most common form of glaucoma. Visual morbidity from PACG, however, was higher. A large majority of the subjects with POAG had not been previously diagnosed and had intraocular pressure within the normal range.
