Abstract

Background: Phacoemulsification is one of the procedures performed in cataract with high-degree myopia patients. Patients with high-degree myopia have a higher risk for postoperative complications due to phacoemulsification which affects their visual acuity. These patients also have higher manifest refraction compared to cataract without high-degree myopia. This study aims to evaluate the success rate of phacoemulsification for cataract in patients with high-degree myopia in National Eye Center, Cicendo Eye Hospital Bandung, Indonesia.Methods: A descriptive study was performed by collecting data from medical records on phacoemulsification in cataract patients with high-degree myopia at the National Eye Center, Cicendo Eye Hospital, during January–December 2011. There were 79 cases out of 136 cases that met the inclusion criterias, those were cataract patients with high-degree myopia who underwent phacoemulsification and patients who did regular follow up visits. Data were analyzed using computer. Results: The results showed that from 79 cases, 44(55.7%) cases involved female patients. Visual acuity after phacoemulsfication increased gradually at 1–2 months follow-up. Eighty one percent cases have been corrected at best with a visual acuity of higher than 6/18. No intraoperative complication occurred in 96.2% of the cases but 3.8% cases had zonular dialysis and vitreous prolaps as intraoperative complication. Meanwhile, corneal edema as postoperative complications occurred in 58.3% of the patients. A total of 17 (21.5%) cases had manifested refraction more than ±2.00 diopter.Conclusions: Phacoemulsification in cataract with high-degree myopia resulted in good visual acuity and minimal complications. However, extreme manifest refraction still occurs in several patients [AMJ.2014;1(1):12–6]Keywords: cataract, high-degree myopia, phacoemulsification Tingkat Keberhasilan Fakoemulsifikasi pada Penderita Katarak yang Disertai Miopia Tinggi di Pusat Mata Nasional Rumah Sakit Mata Cicendo, Bandung, IndonesiaLatar Belakang: Miopia tinggi diketahui berhubungan dengan terjadinya katarak.

Abstract

Background: Advances in pediatric cataract surgery have led to decrease in complication rates, nevertheless additional intraocular surgery (AIS) often still required after pediatric cataract surgery to maximize the outcome. This study aims to review the clinical characteristic of children who underwent AIS in National Eye Center Cicendo Eye Hospital Method: Patient medical records were reviewed retrospectively. Patients then divided into two groups depending on type of AIS. Group A were the children who underwent secondary intraocular lens (IOL) implantation and group B were the children who underwent surgery to repair visual axis opacity. Result: There were 24 eyes in group A and 16 eyes in group B. Mean age at cataract surgery in group A and B were 14.7 and 41.14 months, mean age at AIS in group A and B were 73.8 and 100.3 months, mean time length were 59.6 and 57.6 months in group A and B. Patient in group A had better visual outcome compared to group B. 68.75 % eyes in group B were pseudophakic. Conclusion: Patient in group A had a younger age compared to group B, mean length time between surgery were similar in both group. Patient in group A had better BCVA compared to group B with most of the patients who need VAO surgery were pseudophakic. Keywords: Additional intraocualar surgery, pediatric cataract, secondary IOL

Abstract

Background: Fourth generation of IOL calculation formula (Haigis formula) calculates the ACD which is important in determining the IOL position, so the calculation results expected to be more accurate than the previous generation formula. Haigis formula uses 3 constants that can be updated (optimal/personalized constants). This study aimed to compare the accuracy prediction of cataract surgery refractive results using SRK/T and Haigis formulas (with and without personalized constant).Methods: This is an analytic prospective comparative study. We used 198 medical records data to calculate the Haigis personalized constants. Keratobiometry examinations were performed to 23 eyes using the IOLMaster. The IOL power was calculated using 3 formulas. IOL power selected based on the Haigis formula calculation using personalized constants which gave the most closely result to plano. Best corrected subjective refraction and ME calculated 1 month after surgery.Results: The Haigis personalized constants for this study were a0 = -0.746, a1 = 0.184, and a2 = 0.208. The ME of SRK/T and Haigis formulas (with and without personalized constant) were -0.09±0.48 D, -0.13±0.36 D, and -0,18±0.37 D. ME percentage of SRK/T and Haigis formulas (with and without personalized constant) maximally reached at ±1.25 D, ±1.00 D, and ±1.25 D. Conclusion: The Haigis formula with personalized constants was more accurate than the Haigis formula without personalized constants in predicting the refractive result of cataract surgery. The accuracy of SRK/T formula is equal to the Haigis formula (with and without personalized constants).  Keywords: Haigis formula, SRK/T, personalized constants

Abstract

Pendahuluan : Tajam penglihatan baca dekat adalah salah satu fungsi penglihatan yang dapat diukur menggunakan beberapa isntrumen. Tajam penglihatan baca dekat dipengaruhi oleh kemampuan berbahasa. Kartu tes baca dekat yang tersedia saat ini yang tersedia berbahasa Inggris (Bailey Lovie Word reading chart). Cicendo Word Reading Chart adalah kartu tes baca yang menggunakan Bahasa Indonesia dan memiliki notasi pengukuran LogMAR, M, dan notasi M yang digunakan p;ada jarak baca normal 40 cm. Penelitian ini bertujuan untuk mengetahui kesesuaian pengukuran tajam penglihatan baca dekat tantara dua kartu tes baca tersebut. Metode : Penelitian ini adalah penelitian cross sectional yang mengukur kesesuaian antara dua kartu tes baca dekat. Perbedaan rerata (mean difference) antara kedua pengukuran digambarkan dalam bentuk kurva Bland- Altman. Sampel dari penelitian ini adalah residen Ilmu Kesehatan Mata yang berada di PMN RS Mata Cicendo. Tiga refraksionis mengukur tajam penglihatan jauh dan tajam penglihatan baca dekat melalui dua pengukuran. Hasil : Terdapat 49 sampel pada penelitian ini. Perbedaan rerata antara dua pengukuran adalah 0.0078 dengan batas kesesuaian (limit of agreement) -0.118 hingga 0.113. Koefisien korelasi yang diperoleh adalah 0.35 dengan p value 0.001 sehingga dapat dikatakan bahwa terdapat korelasi yang bermakna secara statistik pada pengukuran dengan menggunakan kedua kartu tes baca dekat tersebut. Kesimpulan : Cicendo Word reading chart dapat digunakan sebagai instrument pemeriksaan tajam penglihatan baca dekat pada lingkungan klinis untuk pasien yang hanya dapat berbahasa Indonesia dengan jarak baca normal 40 cm.
