“…We used the FVA measurement system (AS-28, KOWA, Aichi, Japan), previously reported by Kaido et al to measure the FVA. 30,31 FVA was measured monocularly with best spectacle correction under photopic conditions and natural blinking during a 60-second period. The outcomes assessed were the baseline visual acuity (VA), FVA, visual maintenance ratio (VMR), and blink frequency.…”

Purpose Prelens tear film stability of soft contact lens (SCL) play an important role for contact lens discomfort. In this study, we investigated the association between two types of noninvasive methods and evaluated the tear film stability with SCL using the methods. Patients and Methods In experiment 1, images of ring mire were recorded with a keratograph after focusing the pigment located at the front or back of the SCL. Interferometry and videokeratoscopy were used for the assessment of tear film stability in the right eye of 10 women, with two different cosmetic daily disposable SCLs: polymacon and etafilcon A with polyvinylpyrrolidone. Time to first distortion by noninvasive keratograph break up time (NIKBUT-first) was compared to noninvasive interferometry break up time (NIBUT). In experiment 2, ten normal females wore two different daily disposable SCLs: samfilcon A and narafilcon A. NIKBUT-first and NIBUT were compared between the lenses after 8 hours of SCL wearing. Results In experiment 1, NIBUT-first without SCL was significantly correlated to NIBUT without SCL (r=0.445, P=0.0488, Pearson’s correlation coefficients). However, NIKBUT-first with SCL was not significantly correlated with NIBUT with SCL. In experiment 2, although NIKBUT-first was not significantly different between SCLs, samfilcon A had significantly longer NIBUT than narafilcon A (P=0.0315, paired t -test). Conclusion NIKBUT-first with SCL could be related to tear film stability between the lens and the corneal surface, but not to prelens tear film stability. NIIBUT could be a suitable method to evaluate prelens tear stability.

“…The lower amount of eye drops used in this period might account for an increased tear film stability and thus the visual acuity improvement. 30 To conclude, IOP control by successful CLASS may result in stability of RNFL thickness after CLASS surgery in the investigated period, while a significant IOPreduction was achieved at 12 months postoperatively. Limitation of our study is the relatively small number of patients enrolled.…”

The goal of our study was to investigate changes in intraocular pressure (IOP), best-corrected visual acuity (BCVA), and retinal nerve fibre layer thickness (RNFLT) after CO2 laser-assisted deep sclerectomy (CLASS). Methods: We carried out uncomplicated CLASS surgeries and a 12-month follow-up on 22 open-angle glaucomatous (OAG) eyes of 22 patients. IOP, BCVA, and RNFLT with spectraldomain optical coherence tomography (SD OCT) were recorded before and 1, 3, 6, 12 months after surgery. Results: Mean age of patients was 68.1 years. IOP decreased from preoperative 28.45±5.99 SD mmHg (mean±standard deviation) to 15.09±2.40 mmHg (p=0.00039) at 12 months after surgery. BCVA-change from preoperative 0.34±0.38 SD (LogMAR) to 0.37±0.41 SD (LogMAR) was not significant (p=0.2456). RNFLT-change from preoperative 60.50 ±18.15µm to 59.63±17.52 µm at 12 months postoperatively was not significant (p=0.056). Qualified success rate of CLASS surgery was 72.7%, whereas complete success rate was 64% at 1 year postoperatively. Conclusion: Successful CLASS surgery efficiently reduced IOP. At postoperative 12 months, RNFLT and BCVA were not reduced significantly. There was no significant glaucomatous progression after surgery encountered in respect of investigated parameters.

This study retrospectively evaluated the effect of lutein supplement (LS) on patients with non-proliferative diabetic retinopathy (NPDR). A total of 72 patients with NPDR were included in this study. All patients received Zeaxanthin during the study period. In addition, 36 patients also received LS and were assigned to the treatment group, while the other 36 patients did not receive LS and were assigned to the control group. All patients were treated for a total of 4 months. The endpoints included visual acuity (VA), contrast sensitivity (CS), and glare sensitivity (GS). In addition, any adverse events were also assessed. All endpoints were measured before and after 4-month treatment. Before treatment, there were no significant differences in VA ( P = .75), CS ( P = .71), and GS ( P = .73) between two groups. After 4-month treatment, there were still no significant differences in all endpoints of VA ( P = .66), CS ( P = .58), and GS ( P = .61) between two groups. No adverse events were recorded in either group. The results of this retrospective study showed that LS may not benefit for patients with NPDR after 4-month treatment. More high quality randomized controlled trials should still be needed to warrant the results of this study.
