Clinical Profile and Visual Outcome of Pediatric Cataract Surgeries in West Malaysia

Purpose: We aim to describe the clinical profile and visual outcome of paediatric patients who underwent cataract surgery in a tertiary ophthalmology referral centre in West Malaysia from 2013 to 2018. Methods: This is a retrospective review of all paediatric patients who underwent cataract surgery in our centre from 2013-2018. Results: A total of 35 eyes from 23 patients were included. There were 10 (43.5%) female and 13 (56.5%) male patients. Twelve patients (24 eyes) had bilateral cataract while 11 patients had unilateral cataract. Sixteen (45.7%) eyes had congenital cataract, followed by ectopia lentis (n=10, 28.6%), traumatic cataract (n=8, 22.9%) and steroid induced cataract (n=1, 2.8%). Three types of intraocular lens (IOL) were implanted: which were posterior chamber IOL (n=22, 62.9%), iris claw IOL (n=12, 34.3%) and scleral-fixated IOL (n=1, 2.8%). Majority of eyes (n=28, 80%) had primary IOL implantation. Twenty-five (71.4%) eyes achieved best corrected visual acuity (BCVA) of 6/12 and better at 6 months post-IOL implantation. There was no statistically significant difference in the BCVA at 6 months post-IOL implantation among the different cataract aetiology, primary or secondary IOL implantation and types of IOL implant. Eight (22.9%) eyes developed post-operative complications, which included posterior capsular opacification (PCO) (n=6, 17.1%), IOL decentration (n=4, 11.4%) and glaucoma (n=1, 2.8%). Nineteen (82.6%) patients required glasses for visual rehabilitation. Conclusion: Majority of the paediatric cataract patients achieved BCVA of 6/12 or better at 6 months post-IOL implantation. The visual outcome among the different cataract aetiology, primary or secondary IOL implantation and types of IOL implanted were similar. PCO was the most common post-operative complication.

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.

Purpose. The purpose of this study is to find prognostic factors associated with low visual acuity in patients experiencing vitreous loss during cataract surgery. Methods. A retrospective, noncomparative, interventional, case study of patients experiencing vitreous loss during cataract surgery. Data collected included demographics, best corrected visual acuity (BCVA), axial length (AL), presence of ocular comorbidity affecting central vision, timing of intraocular lens (IOL) implantation, position of the implanted lens, and the presence of corneal sutures. Low visual outcome was defined as BCVA < 20/40. Results. Overall, 179 patients (60.3% males) with a mean age of 73 ± 12 years and axial length of 23.5 ± 1.3 mm with a mean follow-up of 12 ± 13 months were included. In multivariable logistic regression analysis, low visual outcome was independently associated with persisting postoperative complications (OR 6.25, 95% CI 1.378–30.9), preexisting ocular comorbidities (OR 4.45, 95% CI 1.1–18.00), and secondary intraocular lens (IOL) implant (OR 10.36, 95% CI 1.8–60.00). Conversely, pars plana vitrectomy (PPV) for dislocated fragments of lens material, age > 70 years, gender, axial length, degree of surgeon, corneal suturing, and anterior chamber lens implantation were not found to have significant associations with low visual outcomes ( P > 0.05 ). Conclusions. Low visual outcome after vitreous loss during cataract surgery was associated with ocular comorbidities, secondary IOL implantation, development of cystoid macular edema, and additional surgical complications.

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. As a secondary analysis, we reassess the association of initial congenital cataract surgery times, compliance to amblyopia therapy, and visual outcomes for a long-term follow-up in a secondary IOL implantation. Methods. Retrospective review of records of all infants with congenital cataracts who underwent secondary IOL implantation in the Eye and ENT Hospital of Fudan University from January 1, 2001, to December 31, 2007, and the minimum follow-up period was 5 years. Multiple regression analysis was used and the possible confounding factors were also analyzed to assess the effect on visual outcome. Results. A total of 110 patients (male: 59.1%) were included. The median (min–max) age at cataract extraction and IOL implantation was 7.5 (3.0–15.0) and 35.0 (22.0–184.0) months, respectively, and the average follow-up period was 99.3 ± 23.6 months. The median (min–max) BCVA at final follow-up was 0.20 (0.01–1.00). Compliance to amblyopia therapy was none, poor, and good in 21.8%, 24.5%, and 53.6%, respectively. Postoperative BCVA [logMAR, median (min–max) 0.70 (0.00–2.00)] linearly decreased with increasing cataract extraction time (per month) (β=0.04, 95% CI: 0.03–0.06, p<0.0001) in multivariable models with laterality and compliance to amblyopia therapy adjusted. Good compliance to amblyopia therapy was associated with better BCVA (logMAR) at last follow-up (β=−0.40, 95% CI = −0.53 to −0.27, p<0.0001) with laterality, opacity type, and extraction time adjusted. Conclusions. For Chinese infants with congenital cataract, an earlier primary congenital cataract surgery at an age of 3 to 15 months is associated with a better visual outcome. Good compliance to amblyopia therapy was also significant to visual outcome.

INTRODUCTION: Pediatric eye care, including cataract surgery, has become much more common in Nepal in recent years in tertiary facilities such as the Lumbini Eye Institute (LEI). This study provides the first report of visual outcome and complications after cataract surgery at that Institute. MATERIAL AND METHODS: This is a prospective observational study of all cataract surgical patients <16 years of age between March 1, 2011, and February 28, 2012. Visual outcome was assessed by two optometrists with pediatric eye care training. Clinical data were gathered in a specifically designed pediatric eye program database and demographic data were taken from hospital administrative records. RESULTS: In 2011-12, 334 children (248 boys [74%]) underwent cataract surgery, including 89 Nepali (27%) and 245 Indian (73%) children. In total, 320 (96%), 270 (81%), and 190 (57%) attended their first, second and third follow up visits respectively. Pre-operative visual acuity was <6/60 (91%), 6/60 to <6/18 (7%) and >6/18 (2%). Post-operatively, visual acuity was <6/60(27.5%), 6/60 to <6/18 (36.5%) and 6/18 or better (36%). The mean best corrected visual acuity was 6/38 first follow up, 6/34 second follow up, and 6/30 third follow up. Intraoperative complications were 1.6% pupillary capture and post-operative complications were 35.3% posterior capsular opacification (PCO). CONCLUSION: For 63% of children, visual acuity significantly improved with cataract surgery beyond their presenting vision of <6/60, with over 38% of children achieving visual acuity (>6/18). Follow up beyond one month needs significant improvement to treat postoperative complications particularly posterior capsular opacification.Journal of Universal College of Medical Sciences (2015) Vol.03 No.02 Issue 10Page: 35-38

Background: Pediatric cataracts are major causes of children’s blindness. Surgery has proven to be beneficial in terms of visual function prognosis. Contrast sensitivity evaluation after surgery is as important as visual acuity considering that natural world consists of various objects in low-to-medium contrasts. The purpose of this study is to analyze the difference of contrast sensitivity outcomes based on ages at surgery. Method: Retrospective data of children with pediatric developmental cataract from July 2013 to November 2015 were collected. All children who underwent cataract surgery at 60-months-old or less were randomized into two groups, ≤24 months and >24-to-60 months. Contrast sensitivity was then examined with preferential-looking method using Hiding Heidi low-contrast test face chart. The main outcome measures were contrast sensitivity of both groups. Age-at-evaluation, cataract onset, duration of follow-up, duration of deprivation and visual acuity were also noted. Result: Of 14 children (23 eyes), 11 eyes (47,8%) were in ≤24 months group, 12eyes (52,2%) were in >24-to-60 months group. All eyes underwent cataract extraction and similar type of intraocular lens implantation. Mean age-at-surgery was 28,2 months±16,8 (SD). Mean contrast sensitivity for each group was 47,50 %±42,29 and 18,33%±27,38, respectively, with p-value 0,031. Further analysis of Spearman’s correlation test demonstrated significant negative correlation (rs = -0,559; p = 0,006) between the two groups. Conclusion: There was statistically significant difference in contrast sensitivity between those who underwent surgery at ≤24 months and >24-to-60 months. Children who underwent surgery at older ages tend to have better contrast sensitivity afterwards.

Background: Recent reports indicate that both manual small incision cataract surgery and extra capsular cataract excision surgery with posterior chamber intraocular lens implantation are safe and effective for treatment of cataract surgery, however, manual small incision cataract surgery gives better uncorrected vision. Objectives of the study were to compare intraoperative and postoperative complications, to compare induced astigmatism and to compare the visual rehabilitation.Methods: This is a prospective study of 100 consecutive patients assigned to undergo conventional extra capsular cataract excision surgery (50 cases) and manual small incision cataract surgery (50 cases). Study was done for a period of two years at a tertiary care referral hospital. Institutional Ethics Committee permission was taken. Also the informed consent was obtained from each patient.Results: In conventional ECCE, the most common surgically induced astigmatism was WTR in 73.4% of cases with mean of 2.79 D±1.3 on first day. 70% of cases with mean 2.1 D±1.28 and 64% of cases with mean of 1.86 D±1.14 at six weeks. ATR was common in MSICS group, 83.67% of cases with mean of 1.5 D±0.72 on first day, 86% of cases with mean of 1.03 D±0.6 at one week and 88% of cases with mean of 1.27 D±0.81 at six weeks. The induced astigmatism was less in MSICS group compared to ECCE group at first day but after six weeks there was no much significant difference found. Early visual recovery was better in MSICS groupConclusions: MSICS has definitive advantages over conventional ECCE in terms of early visual rehabilitation, minimal surgically induced astigmatism; no suture related complications and reduced surgical time.

Introduction: Cataract is most common cause of curable blindness worldwide and cataract surgery is most common procedure performed in ophthalmology. Posterior capsular opacification (PCO) is most common complication after cataract surgery which is usually treated with Neodymium-doped: Yttrium Garnet (Nd:YAG) laser posterior capsulotomy or occasionally with a surgical capsulotomy. The incidence and severity of PCO correlates to the type of surgical technique, IOL optic edge designs and IOL materials. Material and Methods: 70 eyes of 64 patients operated for age related cataract were studied in this prospective interventional study. Phacoemulsification was done in 35 eyes and SICS in 35 eyes with hydrophobic single piece biconvex foldable intraocular lens. Patients were followed up at 1, 3, 6, 9 and 12 months for the development of PCO. Clinically significant PCO (loss of 2 or more lines of Snellen’s visual acuity chart) was treated with Nd:YAG laser capsulotomy. Results: The overall incidence of PCO was 22.85%. Amongst the patients who developed PCO, SICS and phacoemulsification was performed in 62.5% and 37.5% patients respectively. Result was statistically significant with p value <0.05 using z test. On first postoperative day, patients operated with phacoemulsification had better visual acuity than SICS. Conclusion: Phacoemulsification can provide early and better visual outcome than SICS and has lower incidence of PCO formation which may be due to difference in irrigation and aspiration and less disruption of blood aqueous barrier than SICS. PCO can be reduced by atraumatic surgery and thorough cortical clean up and capsular polishing.

Aim. To conduct a retrospective analysis of secondary IOL implantation in patients who underwent PK with no simultaneous IOL implantation. Materials and Methods. The retrospective study of the secondary implantation of IOLs was conducted in 46 eyes that underwent a primary operation with PK and cataract/lens extraction with no IOL implantation due to capsule rupture or combining corneal or intraocular complications. The minimum period from PK was 12 months. All secondary IOL implantations were performed from January 2011 to August 2017. Aphakic postkeratoplasty patients were treated using one of the surgical techniques for secondary IOL implantation. In-the-bag IOL implantation was possible if the posterior capsule was complete. If the lens capsule remnants were sufficient to provide secure IOL support, an in-the-sulcus IOL implantation was performed. Scleral fixation was offered in eyes with extensive capsular deficiency or the presence of the vitreous body in anterior chamber. BCVA and expected and achieved refraction were evaluated; we included using two biometry devices, and results were compared. Results. The corrected distance visual acuity (CDVA) before surgery ranged from 0.1 to 0.8 (mean 0.54 ± 0.17). After secondary IOL implantation, CDVA ranged from 0.2 to 0.8 (mean 0.43 ± 0.14) at postoperative 1 month and from 0.3 to 0.9 (mean 0.55 ± 0.15) at postoperative 6 months (p<0.05). Comparison of the final refraction using two methods of biometry showed no statistically significant difference in the group that underwent scleral fixation of the IOL, similar to the findings for the in-the-bag and in-the-sulcus IOL implantation groups. In the scleral-fixation group, p=0.55 for the USG biometry technique and p=0.22 for the OB technique. p values for the IOL-implantation group were p=0.49 and p=0.44, respectively. Conclusion. Both implantation methods are safe for the patients. Final refraction is depending on the technique and indication to keratoplasty. Both biometry techniques deliver precise data for IOL choice.
