BACKGROUND
Quality of life may be negatively impacted following cataract surgery if glasses prescription is delayed. This study aims to confirm the refractive stabilisation time in an Australian population to form the basis for suggesting an appropriate timeframe for spectacle prescription.
METHODS
Participants (51 female and 35 male) were recruited one day after uncomplicated unilateral cataract surgery using a monofocal intraocular lens. Subjective refraction, automated refraction and central corneal thickness were measured at two, four and six weeks post-operatively. A short questionnaire assessing the impact of uncorrected near vision on daily activities was collected at two and four weeks.
RESULTS
There was no significant change in the mean automated or subjective spherical equivalent refraction (p < 0.001), mean corneal thickness (p < 0.001), mean uncorrected distance visual acuity (p < 0.001) or mean uncorrected near visual acuity (p < 0.001) over the six-week study period. At week two, 59 per cent of patients stated that their uncorrected near vision affected their ability to perform daily tasks 'somewhat' or 'a lot', increasing to 75 per cent by week four.
CONCLUSION
Uncorrected near vision affected quality of life for most participants. All measured visual and ocular parameters were stable from two weeks post-operatively. Patients need not wait longer than this for spectacle prescription following uncomplicated unilateral cataract surgery.

Eye (London, England) Apr 2023To evaluate the influence of age on the clinical characteristics of primary rhegmatogenous retinal detachments (RRD).
BACKGROUND
To evaluate the influence of age on the clinical characteristics of primary rhegmatogenous retinal detachments (RRD).
METHODS
We conducted a retrospective review of a prospectively collected dataset. Data regarding adult patients (aged 16-100 years) who had undergone primary RRD repair, were extracted from two online databases. Baseline demographics, preoperative clinical characteristics and surgical management details were collected. Age-based groups (16-30, 30-39, 40-49, 50-59, 60-69, 70-79, ≥80) were compared using univariate analysis, with multivariate testing for interaction of age with sex, laterality and pseudophakia.
RESULTS
In total, 8,133 eyes were analysed, of which the majority (59%) were in the 50-69 age-range peaking at 60, with a male predominance (64%). Myopia was significantly more frequent in patients aged <50 years. The presence of posterior vitreous detachment increased up to 50 years, then remained >95%. Foveal involvement, grade C proliferative vitreoretinopathy, total RD and greater RD extent were more common and progressively increased after 60 years, with worsening visual acuity. Isolated superior RRDs became more prevalent with age reaching a plateau in the age-range 50-69, before reducing again; conversely, isolated inferior RRDs were commoner in those <30, with a minimum in the 70-79 age-range. The incidence of fellow-eye RRD decreased linearly with age.
CONCLUSIONS
Age appeared a key variable in RRD phenotype influencing a wide range of RRD characteristics. The higher incidence of myopia, PVD absent and bilateral RRD in patients <40 years and the significant phenotypical differences in the under 40 and over 50 age-groups highlight that there are several discrete forms of RRD.

Review
The correction of presbyopia and restoration of true accommodative function to the ageing eye is the focus of much ongoing research and clinical work. A range of accommodating intraocular lenses (AIOLs) implanted during cataract surgery has been developed and they are designed to change either their position or shape in response to ciliary muscle contraction to generate an increase in dioptric power. Two main design concepts exist. First, axial shift concepts rely on anterior axial movement of one or two optics creating accommodative ability. Second, curvature change designs are designed to provide significant amplitudes of accommodation with little physical displacement. Single-optic devices have been used most widely, although the true accommodative ability provided by forward shift of the optic appears limited and recent findings indicate that alternative factors such as flexing of the optic to alter ocular aberrations may be responsible for the enhanced near vision reported in published studies. Techniques for analysing the performance of AIOLs have not been standardised and clinical studies have reported findings using a wide range of both subjective and objective methods, making it difficult to gauge the success of these implants. There is a need for longitudinal studies using objective methods to assess long-term performance of AIOLs and to determine if true accommodation is restored by the designs available. While dual-optic and curvature change IOLs are designed to provide greater amplitudes of accommodation than is possible with single-optic devices, several of these implants are in the early stages of development and require significant further work before human use is possible. A number of challenges remain and must be addressed before the ultimate goal of restoring youthful levels of accommodation to the presbyopic eye can be achieved.

Comparative Study Randomized Controlled Trial
PURPOSE
To study the endothelial cell morphology and corneal thickness changes after phacoemulsification by using the OZil torsional and longitudinal ultrasound techniques (Infiniti Vision System, Alcon Laboratories).
SETTING
Department of Ophthalmology, Clinical Center, University of Debrecen, Debrecen, Hungary.
METHODS
52 patients with cataract were randomly assigned to longitudinal ultrasound and torsional mode group. All surgeries were performed through a 2.2 mm clear corneal incision, the method employed being divide and conquer. The endothelial morphometry such as cell density (ECD), mean cell area, coefficient of variation of cell area, and central corneal thickness were examined with specular microscopy (EM-1000, Tomey) preoperatively and 4, 8 weeks postoperatively.
RESULTS
ECD values decreased significantly in both surgical groups (P < .001, repeated- mesures ANOVA), the postoperative endothelial cell loss was higher in the longitudinal ultrasound mode group (3.5% and 6.5%, at 4 and 8 weeks after surgery) than in the torsional group (3.3% and 5.5%, at 4 and 8 weeks after surgery), the difference not being significant between the two groups (P = .164 and P = .479, at 4 and 8 weeks after surgery, Mann-Whitney test). There was no statistically significant difference in any of the assessed parameters between the two surgical groups (P > .05). No significant correlation was found between the endothelial cell loss and the nucleus density.
CONCLUSIONS
Both phacoemulsification techniques were safe and effective. The torsional handpiece performs oscillatory movements and delivers less energy into the eye than the longitudinal ultrasound technique, therefore providing more favorable energy and thermal safety profile.

PURPOSE
To evaluate visual outcome and patient satisfaction following Lentis Comfort intraocular lens (IOL) implantation.
METHOD
This retrospective case series examined 68 eyes of 41 patients (mean age 72.0 ± 8.1 years) who underwent Lentis Comfort (LS-313 MF15, Oculentis GmbH, Berlin, Germany; Santen, Osaka, Japan) implantations. Patients were evaluated for visual acuity (VA) at several distances (0.3, 0.5 and 5 meters), refractive error, defocus curve and contrast sensitivity, in addition to answering a questionnaire on photic phenomena, visual discomfort and patient satisfaction.
RESULTS
Uncorrected visual acuity was 0.05 ± 0.13 (logMAR) for distance, 0.23 ± 0.17 (logMAR) for intermediate, and 0.52 ± 0.20 (logMAR) for near. Defocus curve showed the binocular visual acuity attained was almost 20/20 within the range of +0.5 D to -1.5 D. Contrast sensitivity was within the normal range. The Lentis Comfort IOL tolerated astigmatism to some extent. Patient age could potentially be related to uncorrected visual acuity. Questionnaire results showed almost all patients were satisfied with Lentis Comfort IOL implantation.
CONCLUSION
Lentis Comfort IOLs provided better visual function at far and intermediate distances.

Review
The development of subretinal fluid is governed by a limited number of anatomical factors and gravity. As a result, rhegmatogenous retinal detachments form in a predictable manner around the retinal break of their origin. The shape of the detachments points to the position of the break. The purpose of this review is to describe the characterstic contours of subretinal fluid in rhegmatogenous retinal detachments, and to highlight some rules and methodology which can help in the detection of the retinal break in phakic, psuedophakic and recurrent retinal detachments.

PURPOSE
Contemporary cataract surgery is increasingly customizable with the advent of presbyopia-correcting intraocular lenses (IOLs) and the femtosecond laser. The purpose of this study was to determine the types of IOLs ophthalmologists choose for themselves and whether demographic characteristics, surgical experience, and attitudes of ophthalmologists might influence their decision-making. Additional goals included evaluating the use of femtosecond laser use in cataract surgery and investigating surgeon IOL preferences for their patients.
METHODS
We distributed a 29-question Survey Monkey survey to senior ophthalmology residents and practicing ophthalmologists and received 347 responses during a 1-month period. We analyzed 328 surveys using chi-square tests and Fisher's exact tests.
RESULTS
Main outcome measures included surgeons' personal preferences for choice of IOL, femtosecond laser-assisted cataract surgery, and IOL preference for patients. In the setting of no astigmatism, 61.3% of respondents would choose a monofocal IOL set for either distance or monovision for their own surgery. For corneal astigmatism >1.25 D, 60.3% of respondents would choose a toric monofocal lens and only 6.9% would want a femtosecond laser or manual LRI for their own surgery. Of the respondents, 34.6% perform femtosecond laser-assisted cataract surgery, but only 15.3% would want femtosecond cataract surgery performed on themselves. Also, 67.7% implant presbyopia-correcting IOLs (diffractive echelette, multifocal, or accommodative). When correcting for patients' corneal astigmatism >1.25 D, 65.7% of respondents preferred a toric monofocal IOL.
CONCLUSION
Ophthalmologists value quality of vision and are risk averse. Overall, a surgeons' personal preference for their own surgery is correlated with past surgical experience with patients.
