Tajam penglihatan adalah daya lihat yang mampu dilakukan seseorang. Tajam penglihatan normal adalah apabila seseorang dapat melihat huruf, angka, maupun bentuk dalam berbagai macam ukuran pada kartu Snellen dengan jarak 20 kaki (20/20). Katarak merupakan salah satu penyebab terjadinya gangguan penglihatan terbanyak kedua setelah gangguan refraksi yang tidak terkoreksi. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang mempengaruhi timbulnya low vision setelah operasi bedah katarak di Rumah Sakit Muhammadiyah Palembang. Penelitian ini menggunakan desain penelitian deskriptif kuantitatif dengan pendekatan cross sectional menggunakan data rekam medis pasien yang sudah menjalani operasi katarak di Rumah Sakit Muhammadiyah Palembang periode Januari 2017-April 2018. Besar sampel penelitian ini adalah 31 orang. Hasil penelitian ini menunjukkan bahwa pada kontrol keempat pasca operasi, ada 38,7% subjek yang tetap memiliki low vision. Subjek penelitian sebagian besar terdiri dari individu lansia akhir (74,2%), terdapat 2 orang subjek yang mengalami komplikasi intra operasi (6,4%), dan terdapat 9 orang subjek yang mengalami komplikasi pasca operasi (29,1%). Timbulnya lowvision setelah operasi katarak tidak dipengaruhi oleh usia (p = 1,000) dan komplikasi intraoperasi (p = 1,000), namun dipengaruhi oleh adanya komplikasi pasca operasi (p = 0,043). Faktor risiko timbulnya lowvision pasca operasi katarak adalah adanya komplikasi pasca operasi. Oleh karena itu, perlu upaya pencegahan dari berbagai sisi agar tidak terjadi komplikasi pasca operasi katarak.

Objectives: To investigate the clinical characteristics of cataract patients with small pupils and to evaluate the result of cataract surgery on the eye have small pupils by phacotechnique. Subjects and methods: Descriptive study, prospective, uncontrolled interventions. Sample selection. The sample size of 70 patients with 70 eyes of cataracts with small pupils was treated by phaco technique and intraocular lens implant within posterior chamber. Follow up to 3 months. Results: 70 eyes, the percentage of men and women was not different from 54.2% (38 male) compared to 45.8% (32 female). The mean age was 80 ± 8.74, from 58 to 99 years. The disease was mainly found in the age group over 70 years old with over 80% (51.5%). Visual acuity before surgery was very poor under 3m CF (count finger) for 68.6% (48/70). Visual acuity over 1/10 was only a small amount with 2.8% (2 eyes). Pseudoexfoliation was the most common reason complications of mydriasis with 32/70 eyes (45.7%) and 22/70 eyes (31.4%) for age. The preoperative pupilarysizewas mostly small with 63/70 eyes (90.0%), non-dilated pupils (7/70 eyes) (10.0%). Average pupil size was 3.34 mm (2 - 4mm). Iris condition: iris atrophy 20/10 eyes (28.6%), iris synechiae 11/10 (15.7%), irregular iris muscle with 51, 4% and good iris muscle accounted for 48.6%. Grade of cataract: Grade III: 31/70 eyes (44.3%), Grade IV: 32/70 eyes (45.7%), Grade II: 5/70 eyes (7.1%) and V:2/70 eyes (2.9%). Pupil expander technique: OVD injection with 42/70 eyes (60%), using iris hook with 23/70 eyes (32.9%). Pupillary size before and after intervention has changed from 3.7mm to 4.48mm. Conclusions: Iris expander techniques have been shown to have good dilated pupils: 60.0% OVD injection, iris hook was 32.9%, other methods 7.1% One-week visibility of good visual acuity was higher than that of postoperative one day (12.2%) and increased at 1 month and 3 months (20.0%). Very good visual acuity was not available and low vision group was 1.4% after 3 months. Key words: cataract surgery; phacoemusification, small pupil
