To report the effectiveness, patient satisfaction, and complication rate with a zonal refractive intraocular lens (IOL) in high volume of patients.Private clinic, London, United Kingdom.Case series.Retrospective data patients binocular Lentis Mplus IOLs were analyzed. The main outcome measures uncorrected distance visual acuity (UDVA), near (UNVA), corrected acuity, manifest refraction, complications. One-month, 3-month, 6-month analyzed.The study comprised 9366 eyes 4683 patients. mean...
To evaluate the effect of residual astigmatism on postoperative visual acuity and satisfaction after intraocular lens (IOL) surgery.Private practice, United Kingdom.Retrospective case series.Postoperative data patients who had previously undergone refractive exchange or cataract surgery were used in a multivariate regression model to assess 3 months monocular uncorrected distance (UDVA) patient satisfaction. The analysis was based refraction dominant eye each patient. Odds ratios calculated...
PURPOSE: To assess efficacy, safety, predictability, and patient satisfaction after refractive lens exchange with a new rotational asymmetric multifocal intraocular lens. METHODS: One hundred six eyes of 53 patients bilateral the SBL-3 (Lenstec, Inc., Christ Church, Barbados) implantation were evaluated. The mean preoperative sphere was +1.06 ± 2.63 diopters (D) (range: −8.25 to +5.00 D) cylinder −0.51 0.46 D −2.00 0.00 D). Monocular binocular uncorrected corrected distance visual acuity,...

Purpose: To assess the safety, efficacy, predictability, and refractive outcome of implanting Ophtec Artisan phakic intraocular lenses (pIOLs) in eyes with keratoconus. Methods: In this retrospective study, 18 11 patients diagnosed keratoconus who underwent toric or myopic pIOL implantation were followed for 1 year postoperatively. Mean patient age was 41±10.97 years (range: 23 to 64 years). Preoperative manifest sphere −4.64±2.74 diopters (D) −9.75 0.00 D) cylinder −3.07±2.04 D −7.75 −0.50...
To report the outcomes of correction mixed astigmatism with non-penetrating femtosecond laser intrastromal astigmatic keratotomy in patients previous refractive surgery.One hundred twelve eyes that had low after excimer surgery, lens exchange, or phakic intraocular implantation underwent using paired symmetrical arcuate keratotomies created 60 μm from surface to 80% depth at 7 mm diameter. Outcome measures included uncorrected distance visual acuity (UDVA), corrected (CDVA), subjective...
Nile crocodile ( Crocodilus niloticus ) mass mortality events in the Olifants River between Letaba confluence South Africa and Lake Massingir Mozambique have been attributed to pansteatitis: a disease that affects fat depots of animals. The is also found sharptooth catfish Clarias gariepinus same area, cause pollution. Although Valley polluted, impact interventions such as dam construction on biodiversity receives little attention. We show onset pansteatitis epidemic crocodiles at...
To provide an initial retrospective evaluation of early postoperative outcomes after wavefront-guided myopic LASIK using a new-generation Hartmann-Shack wavefront sensor.A noncomparative, study 243 eyes 126 patients that underwent primary LASIK, data obtained with new aberrometer (iDesign Advanced WaveScan aberrometer; Abbott Medical Optics, Inc., Santa Ana, CA). Visual acuity, refraction, and patient satisfaction were evaluated 1 month surgery.The manifest spherical equivalent was reduced...
To determine the safety and efficacy of wavefront-guided LASIK for correction low to moderate myopia, as performed by surgeons employed Optical Express, a large corporate provider.Data were extracted from Express central database on 22,900 patients (42,143 eyes) who underwent primary treat myopia and/or astigmatism. All treatments used ablation profile had refractive target emmetropia. Outcomes evaluated using 1-month follow-up data, which available 32,569 eyes 17,713 (77% follow-up)....
To determine the relationship between low-light pupil size and patient-reported outcomes 1 month after wavefront-guided LASIK in young patients with myopia.Retrospective case series of 10,944 eyes 5,563 myopia who underwent (6.0-mm optical zone). Preoperative was measured under conditions an infrared pupillometer. Visual refractive were evaluated at postoperatively. A questionnaire administered to assess including satisfaction procedure, night driving, glare halo visual symptoms.The average...
To analyze results of wavefront-guided laser vision correction retreatments performed either by lifting the original flap or surface ablation over flap.Optical Express, Glasgow, United Kingdom.Retrospective case series.This retrospective study included patients grouped according to whether they had lift enhancement photorefractive keratectomy (PRK) LASIK flap. All retreatment procedures were with Visx Star S4 IR excimer profile derived from iDesign aberrometer. Visual acuities, refractive...
To evaluate the efficacy, safety, predictability, and patient satisfaction after refractive lens exchange with a zonal intraocular (IOL) an inferior reading addition in emmetropic patients.Optical Express, London, United Kingdom.Retrospective case series.Emmetropic presbyopic patients who had implantation of Lentis Mplus LS-313 MF30 IOL were evaluated. Inclusion criteria sphere between -0.50 diopter (D) +1.00 D no more than 0.75 cylinder uncorrected distance visual acuity (UDVA) 6/6 or...
PURPOSE: To compare clinical and quality of life outcomes between patients who underwent monovision LASIK refractive lens exchange. METHODS: The study comprised 590 with exchange 608 available for 3-month postoperative visits. All had a Tecnis Symfony (Johnson & Johnson Vision Care, Inc., Santa Ana, CA) in at least one eye. Patients were divided into four categories: moderate to high myopia, low plano presbyopia, hyperopia. Three-month data compared each group. RESULTS: Postoperatively,...
To assess vision-related, quality-of-life outcomes 5 years after laser in situ keratomileusis (LASIK) and determine factors predictive of patient satisfaction.Optical Express, Glasgow, Scotland.Retrospective case series.Data from patients who had attended a clinical examination LASIK were analyzed. All treatments performed using the Visx Star S4 IR excimer laser. Patient-reported satisfaction, effect eyesight on various activities, visual phenomena, ocular discomfort evaluated...
To evaluate outcomes and the incidence of adverse events (AEs) in patients who underwent bilateral same-day refractive lens exchange (RLE).Retrospective case series.Patients a private intraocular surgery provider United Kingdom RLE both eyes on same day with treatment dates between March 2018 December 2021.Clinical AEs were collected for continuous cohort undergoing (in absence visually significant cataracts) or had mild cataracts (corrected visual acuity ≥ 20/40). One-month clinical...
Abstract Interspecific interactions can influence species' activity and movement patterns. In particular, species may avoid or attract each other through reactive responses in space and/or time. However, data methods to study such have remained scarce were generally limited two interacting species. At this time, the deployment of camera traps opens new opportunities but adapted statistical techniques are still required analyze interaction patterns with data. We present multivariate Hawkes...
