TLDR
Gains in visual functioning and quality of life (health and vision related) have been demonstrated following cataract surgery and were sustained at 1 year after surgery to the first eye, with additional gains being conferred if second eye surgery had been performed.Abstract:
AIMS: To describe the impact of cataract surgery in terms of visual function (functioning in everyday life with respect to vision dependent activities) and health related quality of life. METHODS: An observational, longitudinal study of patients undergoing cataract surgery was carried out at three district general hospitals in outer London districts of North Thames Region with follow up at 4 and 12 months postoperatively for a clinical assessment and a standardised administered interview. Patients were admitted for surgery to the first eye for age-related cataract between 1 May 1993 and 31 August 1994. Visual functioning was assessed by the VF-14, health related quality of life was assessed by the sickness impact profile (SIP), and vision related quality of life was assessed by VR-SIP (a modification of the generic SIP). RESULTS: Significant gains in all the outcome measures were demonstrated at 4 months postoperatively. No significant change (gain or loss) was observed between 4 and 12 months after surgery to the first eye. Postoperatively, the mean visual function (VF-14) scores, and health related (SIP) and vision related (VR-SIP) quality of life scores, indicated less reported trouble with vision dependent activities and better perceived quality of life, respectively. The average gains in visual function and quality of life (health and vision related) were apparent in groups with good visual outcome and poor visual outcome. Significant additional gains were seen at 1 year in patients who had second eye surgery in the interval between the postoperative assessments. CONCLUSIONS: Gains in visual functioning and quality of life (health and vision related) have been demonstrated following cataract surgery. These gains were sustained at 1 year after surgery to the first eye, with additional gains being conferred if second eye surgery had been performed. Assessment of the outcomes of cataract surgery by clinical indicators alone may underestimate the overall benefits of surgery, particularly in patients with poor visual outcome.read more

Age-related cataract.
TL;DR: Advances in surgical removal of cataracts, including small-incision surgery, use of viscoelastics, and the development of intraocular lenses have made treatment very effective and visual recovery rapid in most cases, but no method to halt the formation of a cataractous lens has been shown to be effective.

Falls and health status in elderly women following first eye cataract surgery: a randomised controlled trial
Rowan H. Harwood,Alexander J E Foss,Francis Osborn,Richard M. Gregson,Anwar Zaman,Tahir Masud +5 more
TL;DR: First eye cataract surgery reduces the rate of falling, and risk of fractures and improves visual function and general health status, and activity, anxiety, depression, confidence, visual disability, and handicap all improved in the operated group compared with the control group.

Multifocal versus monofocal intraocular lenses after cataract extraction
TL;DR: In this article, the authors evaluated the visual effects of multifocal IOLs in comparison with the current standard treatment of monofocal lens implantation and found that people receiving multifocal lenses may be less spectacle dependent (RR 063, 95% CI 055 to 073; eyes = 1000; studies = 10).

TL;DR: The VF-14 is a reliable and valid measure of functional impairment caused by cataract and provides information not conveyed by visual acuity or a general measure of health status.

The sickness impact profile: validation of a health status measure.
TL;DR: Differences among the correlations obtained for each criterion measure with SIP score are discussed in terms of the need for the development of criterion measures that can be expected to differentially relate to the constructs inherent in the SIP.
