Visual Disturbances

Objective. To evaluate intraocular scattering in eyes with posterior capsule opacification by means of an objective scatter index (OSI) obtained from double-pass images of optical quality assessment system (OQAS TM II) and to determine the indication for laser capsulotomy when patients report visual disturbances without decreased visual acuity. Methods. In this prospective, observational, and nonconsecutive case series study, a total of 32 eyes of 29 patients are diagnosed with posterior capsule opacification after age-associated cataract were analyzed. Patient examination included age, the period after cataract surgery, logMAR best corrected visual acuity (BCVA), and OSI. Results. We found a significant decrease in the BCVA and increase in the OSI with the development of posterior capsule opacification. The decrease of BCVA was statistically correlated with the increase of OSI (r=0.812, P<0.01). In patients who reported visual disturbances without decreased visual acuity, OSI decreased to <1.3 and subjective symptoms were resolved in all cases although there was no significant improvement in visual acuity after laser capsulotomy. Conclusions. The results of our study showed that OSI is also a useful parameter for objectively evaluating posterior capsule opacification. OSI may help predict laser capsulotomy in patients who report visual disturbances without decreased visual acuity.

Case Series Study

OBJECTIVES: To determine the frequency of complications following cataract surgery in diabetic patients admitted in the ophthalmology unit. METHODOLOGY: A prospective descriptive interventional case series study was conducted after approval of the ethical committee, from June 2017-June 2020 at the Ophthalmology department MTI-MMC. A total of 129 patients from either gender were enrolled in study. All the study patients went through detailed history and complete ocular examination. After necessary investigations, surgical procedure was carried out. Results were analyzed through the SPSS-24 version. RESULTS: Out of the total 129 eyes of the diabetic patients, fifty-nine (45.7%) were males and seventy (54.3%) were females with a ratio of 1:1.2. Uveitis leads the chart in complications found in twenty (15.50%) eyes while PODR being the least common found in only ten (7.75%) eyes. Worse visual acuity was observed in fourteen (10.85%) eyes. Striate keratopathy and posterior capsule opacification were found in sixteen (12.40%) and fifteen (11.62%) eyes respectively. Among the patients, 15.7% were having more than one complication during follow-up visits and eighty-eight (68.2%) eyes were found to have none complication. The age group 51-60 years observed frequent complications as compared to other groups. Similarly female gender (38.57%) has frequent complications as compared to males (2.7%). CONCLUSION: The study concludes Uveitis as the most common complication observed in 15.50% 0f the eyes while worse visual acuity (10.85%) and progression of diabetic retinopathy (7.75%) being the least common. Striate keratopathy was found in 12.40% while posterior capsule opacification in 11.62% of the eyes.

Objective: Posterior capsule opacification (PCO) is the most common postoperative consequence of cataract surgery which may cause visual acuity reduction. The incidence of PCO in Indonesia has not been reported yet. The objectives of this study were to evaluate three years cumulative incidence of PCO and factors associated with PCO formation at Cipto Mangunkusumo (CM) Hospital. Methods: This was a retrospective descriptive study to patients with uneventful senile cataract surgery in year of 2010. All related data were retrieved from those medical records in year of 2013, which included patient demographics, type of surgery, time of PCO stated, IOL characteristics (material, optic edge design and diametere. Best corrected visual acuity (BCVA) pre operatively, when PCO was determined and Nd:YAG laser (Neodymium- doped yttrium aluminium garnet) was performed in decimal. Result: A total of 578 eyes (485 patients) was involved in this study. Three years cumulative incidence of the PCO was 8.82% (51 eyes). Phacoemulsification surgery was conducted in 496 (85.8%) eyes. The median time to PCO was being determined was 21 months (range 1 to 34 months) with the mean of BCVA was 0.50±0.26. Age, gender, and type of surgery had no related factors to PCO, but higher evidence in using of hydrophilic acrylic IOL (10.7%) was found. After laser Nd:YAG laser was performed, BCVA was improved. Conclusion: Three years cumulative incidence of PCO was 8.82% and there was no defined related factor to PCO reformation, but eye had been using hydrophilic acrylic IOL seem to be higher percentage

Background: Posterior capsule opacification (PCO) is the most common postoperative consequence of cataract surgery which may cause visual acuity reduction, yet the incidence in Indonesia has not been reported. The objectives of this study were to evaluate three years cumulative incidence of PCO and factors associated with PCO formation at Cipto Mangunkusumo Hospital, Jakarta.Methods: This was a retrospective descriptive study on patients with uneventful senile cataract surgery during year 2010. All related data were retrieved from medical records in year 2013, which included patient demographics, type of surgery, intraocular lens (IOL) characteristics (material, optic edge design and diameter). Moreover, time to first PCO diagnosis (month), and best corrected visual acuity (BCVA) pre-operatively, at time PCO was diagnosed and two weeks after Neodymium-doped yttrium aluminum garnet (Nd:YAG) laser were noted (decimal).Results: A total of 578 eyes (485 patients) were involved in this study. Three years cumulative incidence of the PCO was 8.82% (51 eyes). Phacoemulsification surgery was performed in 496 (85.8%) eyes. The median time to PCO diagnosis was 21 months (range 1 to 34 months), mean of BCVA was 0.50 ± 0.26. Age (<65 and >65 years old) was not associated to PCO. Higher incidence of PCO was found in patients using hydrophilic acrylic IOL (10.7%) than in hydrophobic acrylic (6.2%). After Nd:YAG laser was performed, BCVA was improved to 1.00.Conclusion: Three years cumulative incidence of PCO was 8.82% and there was no defined factor related to PCO formation, but higher percentage of PCO occured in patients using hydrophilic acrylic IOL than in hydrophobic acrylic.

Visual Range

Corrective lenses are normally prescribed to correct the refractive errors of the eyes to give good visual acuity at distance (6 m). When presbyopia is present, a convex lens addition (bifocal power) may be included as part of the near correction to move the near focussing point back into the normal reading range (36 to 46 cm). The advantages gained by these corrections may be minimal, or even detrimental, to visual acuity at the intermediate range. A study was undertaken to determine the functional visual acuity of presbyopic individuals at the intermediate visual range with and without the best near and best distant vision corrections.
