Summary: This study investigated the visual improvement achieved with a specific model of scleral contact lens in keratoconus eyes and identified predictors for such improvement. The findings demonstrated that the evaluated scleral contact lens effectively improved visual acuity and corrected ocular aberrations. The visual acuity improvement could be predicted based on pre-fitting variables.

Summary: A study of 2806 eyes found that using scleral or rigid gas permeable contact lenses can significantly reduce the risk of keratoplasty, with patients who successfully use contact lenses having almost one-fifth the risk of undergoing keratoplasty.

Summary: The study compared the performance of a modified contact lens with enhanced optics to correct coma aberration with a conventional lens in keratoconus patients. Results showed that the modified lens significantly outperformed the conventional lens in correcting coma aberration and maintaining optical center closer to the pupil center.

Summary: The study investigated the impact of front surface eccentricity (FSE) of scleral lenses (SLs) on corrected distance visual acuity (CDVA), contrast sensitivity (CS), and higher-order aberrations (HOAs) in keratoconic eyes. Different eccentricity values of SLs were tested and found to significantly improve CDVA and CS, as well as reduce HOAs. Practitioners should consider utilizing this distinct feature of SLs to enhance visual performance in keratoconus patients.

Summary: This study aimed to investigate the corneal alterations in patients with keratoconus who wore scleral contact lenses (ScCLs), with a specific focus on corneal endothelial assessment. The results showed that there were no adverse effects on the cornea or endothelium over a 90-day period of wearing ScCLs, and there was no evidence of disease progression.

Summary: This study investigates the conjunctival vascular density in Scleral Contact Lens (ScCL) wearers using Anterior Segment Optical Coherence Tomography Angiography (OCTA). The results suggest that repeated use of ScCL can cause vascular alterations in the conjunctiva, possibly due to prolonged limbal indentation.

Summary: This study describes the prescribing patterns of therapeutic scleral lenses (SLs) for the management of corneal irregularity and ocular surface disease. Results showed that scleral lenses were most frequently considered as the first choice for corneal irregularity, followed by corneal rigid lenses. For ocular surface disease, lubricant drops were most frequently used as the first treatment option, followed by meibomian gland expression, topical cyclosporine or lifitegrast, topical steroids, punctal plugs, and SLs.

Summary: This study aimed to evaluate the improvement in quality of life for patients with keratoconus fitted with scleral lenses, showing that visual acuity and NEI-VFQ 25 scores improved significantly after fitting. Factors such as disease severity and visual gain were found to be associated with improvements in quality of life.

Summary: This pilot study aimed to evaluate the effect of increasing corneal clearance after fitting a specific model of scleral contact lens (ScCL) on refraction and optical quality in healthy subjects. The results showed significant changes in refraction and high-order aberrations with increasing sagittal heights of ScCLs.

Summary: In this work, a new diffractive trifocal intraocular lens design is proposed, which aims to provide high visual performance at intermediate distances. The design is based on a fractal structure known as the Devil's staircase. Numerical simulations and experimental tests confirm the design's effectiveness at intermediate distances, its low pupil-dependence, and its stability against decentering.

Summary: This study investigated the international prescription and management practices of scleral lenses across multiple practice types. The main indications for scleral lens wear were corneal irregularity (87%), ocular surface disease (9%), and uncomplicated refractive error (4%). The fitting process involved an average of 2.4 lenses ordered during 3.8 visits. The most common landing zone shape was spherical (64%), and a relatively low percentage of patients wore lenses with advanced landing zones or optical designs.

Summary: This study compares the 2-year visual quality of Evolution Implantable Collamer Lens (EVO-ICL) and small incision lenticule extraction (SMILE) for correcting low myopia. The results show that EVO-ICL provides comparable safety, efficacy, long-term visual stability, and high patient satisfaction compared to SMILE. There are some differences in visual quality between the two methods, such as halo after ICL and starburst after SMILE.

Summary: This study compared the optical quality and chromatic performance of different refractive-diffractive intraocular lenses. It found that chromatic aberration correcting lenses had the lowest far-focus dispersion, with one lens being able to reduce eye's chromatic aberration. Another lens increased far-point chromatism, but was comparable to the performance of two other lenses. All the models displayed varying optical quality in response to light color.

Summary: Traumatic injury in pediatric patients often leads to significant refractive errors that can cause amblyopia if left untreated. Scleral contact lenses (ScCLs) are effective in treating these refractive errors, but intolerance may be a limiting factor. While soft contact lenses (SCLs) are well tolerated, they are less effective in treating refractive errors compared to ScCLs.

Summary: Prescription trends for patients with keratoconus were examined, showing an increase in the use of scleral lenses over the past decade. However, corneal gas-permeable lenses remained the most commonly prescribed for these patients. Despite being prescribed for the most advanced cases, scleral lenses provided good visual acuity.

Summary: This study aimed to estimate the outcome of a sociocultural relevant vocal hygiene program in facilitating vocal health among female school teachers. The results showed that the program had a positive effect on improving teachers' awareness of at risk voice behaviors and vocal health, but had limited efficiency in producing physiological improvement in teachers' voice.

Summary: Glottic web refers to the abnormal soft tissue adhesion between the vocal cords due to failure of recanalisation. Severe glottic webs can lead to respiratory distress and require urgent intervention. This study presents a successful management approach involving combined endoscopic excision of the web and laryngofissure approach for keel stenting.

Summary: This study investigates the effects of adjusting T and C levels on behavioral and cortical auditory evoked potentials (CAEP) responses in young children using cochlear implants. The results show that reducing C levels significantly reduces sound field thresholds, speech perception, and CAEP thresholds, while modifying T levels has no significant impact on these measures. Furthermore, a significant correlation is found between sound field thresholds, speech perception, and CAEP measures.

Summary: The aim of this study was to compare postoperative outcomes between KTP-532 LASER assisted tonsillectomy and Coblation assisted tonsillectomy. The results showed that there was no significant difference in postoperative pain between the two groups. However, Group B had less slough formation in the tonsillar fossa and faster mucosalisation compared to Group A. There was no statistical difference in the time taken to resume normal diet.
