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 report provides a historical review and detailed account of the contemporary use of scleral lenses, highlighting them as the optimal choice for contact lens wear across various clinical indications and potentially delaying the need for corneal surgery. It also discusses the challenges and future applications associated with modern scleral lens fitting and evaluation processes.

Summary: The study found that scleral lenses with varying fluid reservoir thickness effectively improved vision and contrast sensitivity, while reducing higher-order aberrations in keratoconic eyes. The thickness of the fluid reservoir should be considered an important factor in providing better vision and contrast sensitivity by minimizing higher-order aberrations and maintaining the normal physiology of eyes with keratoconus.

Summary: The study showed that SPOT scleral contact lenses are an effective and well tolerated method to improve the visual acuity of patients with irregular astigmatism. Most patients continued to wear the lenses daily, with improvements in visual acuity, comfort, quality of vision, and satisfaction.

Summary: This study reported the use of custom-designed scleral contact lens in the treatment of pediatric patients. The main purposes of using scleral lenses were to correct refractive errors and protect the ocular surface. The study found that pediatric patients with advanced keratoconus and traumatic corneal scarring showed the most appreciation for the benefits of scleral lenses.

Summary: Mini-scleral lenses significantly improve visual acuity and visual functioning in patients with keratoconus. Difficulties with lens insertion and removal are the principal reason for lens dropout.

Summary: The study found that scleral contact lenses significantly improved visual acuity in patients with keratoconus, potentially leading to a small increase in intraocular pressure, which may not have a significant impact on otherwise healthy eyes.

Summary: The study aimed to compare the impact of using TOK and STM contact lenses on higher order aberrations in myopic astigmatic eyes, showing that TOK induced higher HORMS, spherical aberration, and coma RMS compared to STM.

Summary: This study found that visual quality significantly improved in eyes with keratoconus when corrected with scleral lenses (SL). However, despite the improvement in visual performance, there were no significant changes in the mfERG responses associated with retinal disease. The use of SL for irregular astigmatism correction helps exclude optical effects induced by keratoconus.

Summary: By calculating equations, this method achieves exact and third-order designs of thick lenses, surpassing the results obtained by optimizing conic constants using commercial optical design software. The method offers improved results for shape factors ranging from -0.5 to 0.9 as the shape of the lens changes.

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: This case series demonstrates the presence of acute focal edema suggestive of corneal hydrops in patients wearing ScCLs with longstanding PKs and recurrent ectasia. Although similar events have occurred as part of the natural history of post-PK corneas for keratoconus, the proximity of ScCL refitting to two of the events suggests some association.

Summary: Corneal biomechanical indices correlated with ocular higher-order aberrations in patients with keratoconus, particularly due to the asymmetrical shape of the cornea causing an increase in coma.

Summary: The purpose of this study was to investigate the optical impact of the change in the vault of two geometries of scleral contact lenses using computational simulations. Ray-tracing simulations were performed using specialized software in three eye models with different levels of primary SA. The results showed that the vault of the lens had an impact on the optical quality achieved for different vergence demands.

Summary: This study explored the factors affecting the linear magnification of the intermediate fundus image during indirect ophthalmoscopy. The results showed that the parameters, such as the power and ametropia of the eye, and the equivalent power and position of the ophthalmoscopy lens, have significant effects on magnification. The magnification values provided by manufacturers are only approximations, and better estimates can be obtained by considering the appropriate parameter values.
