We aimed to introduce a new technique to reduce regional asymmetry of corneal thickness by assessing its effectiveness in four patients with myopic regression after laser refractive surgery (LRS).

Four patients (four eyes) with myopic regression after LRS were included in this study. A new technique of enhancement with laser epithelial keratomileusis-linked laser asymmetric keratectomy using semi-cylindrical ablation pattern (E-LAK-SCAP) with full integration of the Vision-Up software for analyzing the corneal thickness deviation can be used to create central symmetry by blocking laser ablation on the thin cornea. It reduces the regional asymmetry of the corneal thickness, thus improving corneal symmetry and correcting the refractive power and myopic shift due to E-LAK-SCAP. We measured refraction, visual acuity, intraocular pressure (IOP), central corneal thickness (CCT), corneal irregularities in the 3.0mm, and 5.0 zones on Orbscan maps, the sum of corneal thickness deviations in four directions (SUM), ative visual acuity, and blurring was reduced postoperatively. There was no myopic regression in the one-year postoperative period.

To compare visual outcome, higher order aberrations (HOAs) of topography guided and Q value adjusted ablation in the fellow eye of patients undergoing photorefractive keratectomy (PRK) for the correction of myopia and myopic astigmatism.

Prospective randomized controlled interventional clinical study. The eyes of 52 patients undergoing PRK for myopia and astigmatism were included, that is, 104 eyes in total. In each patient, eyes were randomly allocated to group I one eye received topography guided PRK using Contoura ablation software, or group II the other eye received Q value adjusted PRK using Custom Q ablation software.

Six months.

At the end of 6 months, LogMAR UDVA was -0.04 ± 0.12 and -0.05 ± 0.11 (p = 0.688), while LogMAR CDVA was -0.06 ± 0.09 and -0.06 ± 0.1 in group I and group II, respectively (p = 0.972). Both groups showed a progressive oblate shift with time. 3,3cGAMP This oblate shift was insignificantly less in group I by Topolyzer at 6mm, 15° and 30° at 6 months (p = 0.102, p = 0.138, p = 0.24red to CQ PRK.

TG PRK and CQ PRK yielded similar results regarding UDVA, CDVA, MRSE, safety, predictability and contrast sensitivity. Both groups showed a progressive oblate shift, which was less in the TG group but the difference was statistically insignificant. TG PRK showed significantly improved trefoil HOA as compared to CQ PRK.

The amount of protein deposition on soft contact lenses and to what extent the proteins are denatured may have an impact on comfortable wearing times of contact lenses. The purpose of this study was to evaluate the effects of two lens care systems on total protein and the quantity and activity of lysozyme deposited on worn senofilcon A, silicone hydrogel contact lenses.

Thirty symptomatic soft contact lens wearers were enrolled into a 4-week prospective, randomized, bilateral eye, daily-wear, crossover, double-masked study. Participants were fitted with biweekly senofilcon A lenses and were assigned either a polyquaternium-1 and myristamidopropyl dimethylamine-containing system (OPTI-FREE RepleniSH) or a peroxide-based system (CLEAR CARE). After each wear period, proteins were extracted from the lenses and analyzed for total protein, total lysozyme quantity and activity.

The use of either the peroxide-based system or the polyquaternium-1 and myristamidopropyl dimethylamine-containing system resulted in dimethylamine-containing systems were neither statistically nor clinically significant and the overall amounts of denatured lysozyme recovered from the lenses were low ( less then 1 microgram/lens).

This pilot study was undertaken to examine the feasibility of a larger scale trial examining the effect of interventions to improve patient-clinician collaboration. The primary outcome was the extent of clinician-patient collaboration during glaucoma consultations. The secondary outcomes were the results of the Patient Experience Questionnaire and the patients' opinion of how involved they were in decisions about their care and how keen they would be to increase this involvement.

This is an observational study of clinician-patient communication involving 9 glaucoma clinicians and 37 patients attending a glaucoma monitoring clinic. Consultations were videotaped and later assessed for the degree of collaboration. Patients completed a validated Patient Experience Questionnaire and a questionnaire designed to collect the patients' opinion of how involved they were in decisions about their care.

The consultations were largely "clinician centred" with clinicians speaking 58% of the sentences and asking a meanoma consultations remain "clinician-centred" and, in view of the evidence of the benefits of good clinician-patient collaboration, further studies to examine interventions to improve clinician-patient collaboration may be of benefit to glaucoma patients. These interventions could target both clinicians and patients, and many patients in this study indicated they would like to be more involved in decisions about their care and would welcome support in achieving this.

To compare and report the 2-year treatment outcomes from 3 different anti-VEGF treatment regimens in treating neovascular aged-related macular degeneration (nAMD) Ranibizumab pro re nata (Ranibizumab-PRN); Ranibizumab treat and extend (Ranibizumab-T&E); Aflibercept fixed first year dosing (7 injections) with treat and extend in subsequent year (Aflibercept-Fixed).

All treatment-naïve nAMD patients who completed 24 months of monitoring from a single treatment center were included. Patients received the initial loading dose of three injections (4-weekly interval), followed by one of the 3 treatment regimens. Primary outcomes were changes in visual acuity (VA) and central retinal thickness (CRT). Secondary outcome was number of injections required in each year. Data analysis included last observation carried forward (LOCF) for patients with incomplete year-2 follow-up.

A total of 249 eyes (230 patients) were studied 121 Ranibizumab-PRN; 65 Ranibizumab-T&E, and 63 Aflibercept-Fixed. Baseline median VA (ETDRS letters) for Ranibizumab-PRN, Ranibizumab-T&E, and Aflibercept-Fixed was 53.
