Outcomes of cataract surgery at a referral center

Abstract

Purpose:To report the outcomes of cataract surgery at a large referral eye hospital and to identify factors associated with less than excellent visual outcomes.Methods:Hospital records of patients, who had undergone age-related cataract extraction (1,285 procedures) within a two-year period were sampled randomly for 353 patients (405 eyes) and baseline characteristics were recorded. Up to three causes of visual loss (contributory reasons) were considered and the principal cause of “less than excellent outcome,” i.e., best spectacle corrected visual acuity (BSCVA) <20/25 was defined as the primary reason.Results:Mean age of the participants was 68.6 years, and 50.7% of enrolled subjects were female. Phacoemulsification had been performed in 92.1% of cases. Out of 405 eyes, 54%, 78%, and 97% achieved BSCVA of ≥20/25, ≥20/40, and ≥20/200, respectively. Poor visual outcomes were significantly associated with older age (OR: 4.55 for age >70 years), female gender (OR: 4.64), ocular comorbidities (OR: 7.68), surgically challenging eyes (OR: 7.33), long and short eyes (versus eyes with normal axial length, OR: 3.24), and being operated on by a novice surgeon (OR: 2.41). The leading contributory reasons for unfavorable outcome, in descending order were maculopathy (17%), posterior capsule opacification (PCO, 11.8%), corneal opacity (5.7%), and degenerative myopia (5.4%).Conclusion:Maculopathy, PCO, corneal opacity, degenerative myopia and ARMD may contribute to unfavorable outcomes in cataract surgery.

“…Cataract is the leading cause of treatable blindness worldwide 1. Phacoemulsification with intraocular lens (IOL) implantation is the most common surgical procedure performed for the treatment of cataract, with benefits of causing less surgically induced astigmatism and early and better visual rehabilitation 2,3.…”

Patient considerations in cataract surgery &ndash; the role of combined therapy using phenylephrine and ketorolac

“…As we discussed previously, cataract is the leading cause of treatable blindness worldwide and is associated with considerable disability and major economic and social consequences. 5 Global population growth and increasing longevity are expected to double the number of people with visual loss from cataracts by the year 2020. 56 Restoration of vision, through phacoemulsification cataract surgery, has been demonstrated to enhance quality of life as well as to improve household economic status.…”

“… 4 In addition, 75% of people with cataracts live in developing countries where blindness is associated with considerable disability and major economic and social consequences. 5 Cataract surgery is the most common procedure performed by ophthalmic surgeons 6 and is the only effective treatment for cataracts. According to the UK National Health Service, ~330,000 cataract surgeries are performed every year in England.…”

“…In general, these criteria include the reduction of visual symptoms, improvement of visual function, achievement of the desired refractive outcome, and improvement of physical function, mental health, and quality of life. 5 , 6 , 8 However, recent advances in surgical techniques in addition to the improvement of postoperative visual outcomes have progressively changed the primary concern of cataract surgery from the safe removal of the opaque crystalline lens to a procedure refined to yield the best possible refractive result. 9 Emmetropia can be achieved for patients with myopic or hyperopic refractive errors and astigmatism by selecting the appropriate intraocular lens (IOL).…”

“…Cataract surgery is one of the most frequently performed procedures (11)(12)(13)(14)(15)(16)(17)(18). The successful surgical outcome is not defined solely by the safe removal of the opaque lens, but the essential goal is achievement of the best visual and refractive result with maximal postoperative comfort for the patient (19)(20)(21)(22)(23). The modern cataract surgery with phacoemulsification is considered a minor procedure with an uneventful and pain-free recovery period.…”
