Immediate sequential bilateral cataract surgery in adults with Down's syndrome.

PURPOSE: To describe the cataract surgery outcomes in 34 adult patients with Down's syndrome in our center between 1996 and 2019.

SETTING

Clinical practice, tertiary hospital in Madrid, Spain.

DESIGN

Retrospective, descriptive study in which 34 patients with Down's syndrome who underwent cataract surgery in our center between 1996 and 2019 were included.

METHODS

Socio-demographic and clinical data such as the type of cataract, the keratometry and biometry, the type of surgery, the IOL material, and the complications before and after surgery were recovered.

RESULTS

Fifty-four eyes of 34 patients (23 female, 11 male, mean age 49 ± 8 years) underwent cataract surgery with general anesthesia. Immediately sequential, bilateral cataract surgery was performed in 18 patients (90% of bilateral cases). White cataract was found in 11 eyes (20.4%). Phacoemulsification technique was used in 51 eyes, extracapsular technique in 2 eyes (3.7%), and intracapsular technique in 1 eye (1.85%) (the only aphakic eye after surgery). The mean Km was 48.73 ± 4D, and the mean axial length was 25.2 ± 2.5 mm. The most frequent ocular comorbidity was myopia (27 eyes, 50%) followed by strabismus (11 eyes, 20.4%) and keratoconus (10 eyes, 18.5%). Posterior capsular rupture as a complication during surgery was found in 3 eyes (5.5%). The mean preoperative visual acuity was 0.8 ± 0.2 logMAR, and the mean postoperative visual acuity was 0.5 ± 0.18 logMAR.

CONCLUSIONS

Phacoemulsification technique can be performed in adults with Down's syndrome with an acceptable rate of complications. The lack of patient cooperation, the ocular comorbidities and the challenging biometric estimation must be considered in surgical planning. It seems reasonable to perform immediately sequential, bilateral cataract surgery when possible, in order to reduce the exposure to general anesthesia.
