“…This was demonstrated in the study by Denoyer et al, 20,21 in which an aspherical intraocular lens with a negative spherical aberration resulted in reduced ocular spherical aberration and improved mesopic contrast sensitivity, and led to better subjective quality of vision. The lens choice can also be affected by glare disability, as studied by Pandita et al 22 This information, alongside the individuals' personal profile, could be used to help clinicians make more informed decisions.…”

Aims Cataract surgery is one of the most common surgeries performed, but its overuse has been reported. The threshold for cataract surgery has become increasingly lenient; therefore, the selection process and surgical need has been questioned. The aim of this study was to evaluate the changes associated with cataract surgery in patient-reported vision-related quality of life (VR-QoL). Methods A prospective cohort study was conducted. Consecutive patients referred to cataract clinics in an NHS unit in Scotland were identified. Those listed for surgery were invited to complete a validated questionnaire (TyPE) to measure VR-QoL pre-and postoperatively. TyPE has five different domains (near vision, distance vision, daytime driving, night-time driving, and glare) and a global score of vision. The influence of pre-operative visual acuity (VA) levels, vision, and lens status of the fellow eye on changes in VR-QoL were explored. Results A total of 320 listed patients were approached, of whom 36 were excluded. Among the 284 enrolled patients, 229 (81%) returned the questionnaire after surgery. Results revealed that the mean overall vision improved, as reported by patients. Improvements were also seen in all subdomains of the questionnaire. Conclusion The majority of patients appear to have improvement in patient-reported VR-QoL, including those with good preoperative VA and previous surgery to the fellow eye. VA thresholds may not capture the effects of the quality of life on patients. This information can assist clinicians to make more informed decisions when debating over the benefits of listing a patient for cataract extraction.

“…In this study, in an effort to minimize variations in pupil size that can affect performance on these optical and psychophysical tests, wavefront aberrometry was analyzed at fixed 5 mm diameter, and contrast sensitivity was similarly tested after dilation using a 5-mm aperture. As an alternative approach, others have fashioned black soft contact lenses of fixeddiameter apertures [25]. A multivariate analysis was performed to determine the relationship between whole-eye SA and mesopic low-contrast acuity, holding other higherorder aberrations constant.…”

“…Most studies that demonstrated improved spherical aberrations with aspherical IOLs used the Tecnis Z9000 silicone IOL (AMO) [10][11][12] or the AcrySof IQ SN60WF acrylic IOL (Alcon, Fort Worth, TX, USA). 13 In this study, we compared the Tecnis ZA9003 and the Sensar AR40e, both products of AMO. The two A-constants in this case were different because the A-constant depends on the optic shape, which was the only difference between the two IOLs used.…”
