DIFFERENCES IN RESULTS RETINOMETRI PREOPERATIVE WITH POSTOPERATIVE CATARACT

ABSTRACT

Background: Determination of visual acuity after cataract surgery is needed to provide information to patients. In the hazy media conditions such as cataracts, retinometer can measured the potential visual acuity. Retinometry results accuracy were expected to help determining the prognosis of visual acuity cataract patients. The aim of this study was to determine the differences of preoperative retinometri readings towards the postoperative retinometri on senile cataract patients.

Methods: Pretest post test design was performed on senile cataract patients. Subjects who met the inclusion and exclusion criteria were examined preoperative and postoperative retinometry. Cataract will be classified according to the degree of cataract by The cataract epidemiology Japanese cooperative study group system (JCCES). Grade 1 and 2 cataract included within group 1, while for grade 3 and 4 included within group 2. The data was analyzed by the t -test.

Results: Fivety nine eyes of 57 subjects were recruitted during the study. The mean difference in preoperative retinometri results with postoperative in group 1 was 0:05 (p = 0.04) while the mean difference retinometri results in group 2 at 0.23 (p = 0.001 ). There were a significant difference between the results of retrinometri pre surgical and post- surgical retrinometri in groups 1 and 2. The higher the degree of the difference were the greater cataract

Conclusion: The higher the degree of cataract, the most lower the preoperative retinometry compare to post operative retinometry.

ABSTRAK

Latar belakang: Perkiraan tajam penglihatan pasca bedah katarak sangat diperlukan untuk memberikan informasi kepada pasien katarak sebelum operasi.Retinometer dapat mengukur potensial visus pasca bedah katarak pada kondisi lensa yang keruh.Ketepatan hasil pemeriksaan retinometri diharapkan dapat membantu menentukan prognosis penderita katarak. Penelitian ini bertujuan untuk mengetahui perbedaan retinometri prabedah dengan pasca bedah berdasarkan derajat katarak senilis.

Metode: Disian penelitian adalah pre post design yang dilakukan pada pasien katarak. Populasinya adalah penderita katarak senilis dengan sample yang memenuhi kriteira inkulsi dan eksklusi. Subjek yang memenuhi kriteria inklusi dilakukan pemeriksaan retinometer prabedah dengan pupil lebar dan pemeriksaan retinometer pasca bedah. Derajat katarak diklasifikasikan menurut Japanese cooperative cataract epidemiology study group system (JCCES). Derajat 1 dan 2 dimasukan dalam kelompok 1 sedangkan untuk derajat 3 dan

4 dimasukan dalam kelompok 2. Data dianalisis menggunakan t-test.

Hasil: Didapatkan 59 pasien katarak dengan rerata perbedaan hasil retinometri prabedah dengan pasca bedah pada kelompok 1 adalah

0,05 (p=0,04) sedangkan rerata perbedaan hasil retinometri pada kelompok 2 sebesar 0,23 (p=0,001). Terdapat perbedaan bermakna antara hasil retinometri pra bedah dan retrinometri pasca bedah pada kelompok 1 dan 2. Semakin tinggi derajat katarak ,perbedaan tersebut semakin besar.

Simpulan: Semakin tinggi derajat katarak, retinometri prabedah mempunyai nilai yang semakin rendah dibandingkan dengan retinometri pasca bedah.
