Long-time visual functional results of cataract surgery on low vision patients.

Background/aims: To assess longitudinal 5-year results of cataract surgery on low vision patients.

Methods: In this prospective, long-time, observational case-series, we report the outcome regarding the subjective visual function (n = 35) assessed by a visual function questionnaire (VF-14) and the visual acuity (n = 30) of surviving low vision patients 5 years after surgery. We compare with data recorded on the same patients before surgery and 4 months postoperatively.

Tinted contact lenses in Bothnia dystrophy.

Purpose: To determine whether tinted contact lenses can improve visual function in patients with Bothnia dystrophy (BD), a genetically defined retinal dystrophy with prolonged dark adaptation.

Methods: Twelve patients with BD were fitted with the same type of soft contact lenses tinted dark brown. Visual acuity (VA), contrast vision, near vision and visual fields were tested before and 1 month after contact lens fitting.
