“…As regard to the therapeutic indications of scleral lens, the main conditions are scarring diseases of the cornea and conjunctiva (Stevens-Johnson syndrome, ocular cicatricial pemphigoid, cicatricial entropion, and post herpetic keratitis) and cases of severe dry eye (exposure keratopathy, congenital deficiency of the meibomian glands, superior limbic keratoconjunctivitis, and Sjögren syndrome) (8)(9)(10)(11)(12)(13)(14)(15)(16) . This kind of use is related to lacrimal retention between the cornea and lens and ocular protection in cases of exposure keratitis and eyelid or eyelash abnormalities.…”

“…• Lens insertion requires a relative motor skill, with adequate head position and precise hand movements to prevent leakage of the fluid chamber or air bubbles trapped under the lens. Hypoxia is a major concern mainly in some situations such as in post-keratoplasty fitting; may occur in some cases, mainly in lenses made of low-Dk materials, which are rare nowadays; and may be linked to excessive vaulting and/or high-thickness lenses (6)(7)(8)(9)(10)(11)(12)(13)(14) . Thus, scleral lenses are optical and therapeutic devices that may be an excellent option when soft or rigid gas-permeable (RGP) corneal lenses cannot be successfully fit.…”

The aim of this study was to evaluate the fitting process of a scleral lens that allows several parameter adjustments during trials and after the initial period of use. In addition, we verified which adjustments were needed and used the most, their indications, and how often these resources were used, and checked the results. Methods: Scleral contact lens fittings in a private clinic setting were prospectively analyzed in a sequential, non-randomized, and non-comparative manner. All the patients underwent a complete ophthalmic examination and had an indication for scleral lens use (Zenlens, Alden Optical). Results: Scleral fit was analyzed in 80 eyes of 45 patients. Regarding diagnosis, 72% of the patients had keratoconus; 12%, radial keratotomy; 5%, post-refractive surgery ectasia; 5%, dry eye; and 3%, high myopia. In 66 (82.5%) of the 80 eyes studied, parameters were modified when the lenses were ordered. The reasons that led to the modifications were apical touch or decreased sagittal height, increased sagittal height, cylindrical over-refraction, poor visual acuity, lens flexure, peripheral touch, 360° edge compression, horizontal edge compression, and vertical edge compression. Conclusion: In this study, the use of Zenlens scleral lenses was shown to be a promising corrective treatment for patients requiring the use of scleral lenses. Although the study suggests a learning curve, as many adjustments were allowed, the lens could be customized according to the patients' needs. This increased the success rates of fitting and wearing, and consequently, use of the lens became a great option for the visual rehabilitation of patients.

“…Alguns autores descrevem também o uso de LC esclerais, que teriam como indicações visuais em crianças as ectasias corneanas primárias como ceratocone, ceratoglobo e degeneração marginal pelúcida e ainda afacias, altas miopias e pós-operatórios de transplante de córnea. As indicações terapêuticas destas lentes seriam principalmente na síndrome de Stevens-Johnson, mas também no penfigóide ocular cicatricial, ceratopatia de exposição, ceratites pós-herpéticas, Sjögren, deficiência congê-nita das glândulas de Meibomius e a ceratoconjuntivite límbica superior (12) . Para uso contínuo como lente terapêutica em crianças têm-se preferido a lente de contato silicone-hidrogel que se mostra cada vez mais eficaz e segura nessa faixa etária (13) .…”
