“…[272829] In our study, the mini scleral contact lens was successfully fitted in all patients and, the visual acuity improved in all eyes after contact lens fitting. Mean corrected visual acuity by placing the MSD contact lens without over refraction (was 0.09 that was significantly better than mean BSCVA ( P value = 0.007).…”

Purpose:To evaluate the feasibility and efficacy of mini-scleral design (MSD) contact lenses to treat keratoconus patients who were unsatisfied with the results of corneal inlay.Methods:In this prospective interventional case series, 9 eyes of 6 keratoconus patients who were unsatisfied with the results of corneal inlay were fitted with MSD contact lenses. Demographic data, uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), and higher order aberrations (HOAs) were evaluated before contact lens fitting. Corrected visual acuity by placing the MSD contact lens with or without over-refraction, and HOAs were measured one hour after contact lens fitting. One month after contact lens wearing, corrected visual acuity by placing the MSD contact lens with over-refraction and possible contact lens related problems were assessed. Ocular comfort and contact lens handling problems were asked in follow-up visits. The data was analyzed using descriptive statistical tests.Results:Nine eyes of 6 patients were successfully fitted with the mini-scleral lens. Fitting was ideal in 7 eyes and acceptable in 2 eyes. Mean corrected visual acuity by placing the MSD lens without over-refraction was 0.09 (range, 0.00-0.15) LogMAR which was significantly better than the mean BSCVA of 0.38 (range, 0.2-0.6) LogMAR (P = 0.007). The mean root mean square (RMS) of third-order coma and trefoil significantly decreased after MSD contact lens fitting (P = 0.012 and P = 0.015, respectively); however, changes in the fourth-order spherical aberration were not statistically significant (P = 0.336).Conclusion:Mini-scleral contact lenses may be helpful in the management of visually unsatisfied patients after corneal inlay.

“…Corneal or scleral contact lens therapy can be used to promote healing while paying attention to the increased risks of secondary infection and lens-related sterile hypopyon [35,36,37]. The function of the lens is to provide a fluid cushion for the cornea and protect it from the rubbing effects of the lids [38,39,40]. Some authors have noticed an improvement in the cornea through the use of temporary silicone plugs to help increase tear volume [41].…”

Neurotrophic Keratitis

Neurotrophic keratitis (NK) is a rare degenerative corneal disease that occurs as a result of partial or total impairment of trigeminal innervations, leading to a reduction (hypoesthesia) in or loss (anaesthesia) of corneal sensitivity. The impairment of sensory innervation causes a reduction in the lacrimation reflex and the vitality, metabolism and mitosis of epithelial cells, with subsequent deficiency in epithelial repair, stromal and intracellular oedema, loss of microvilli, and abnormal development of the basal lamina. Several recent studies have proposed different therapies based on different aetiopathogenetic theories. The aim of the therapy is to treat aetiopathogenesis and, at the same time, promote corneal healing. In this paper, we report the aetiology, diagnosis, management, and medical and surgical treatment of NK, also indicating future treatments based on the most recent studies.

“…Semi-scleral lenses have a smaller diameter (13-14.6 mm), which leads to a more practical application and a reduced cost. It is considered that scleral lenses can be more effective than semi-scleral lenses because of the formation of a large fluid reservoir over the cornea; however, Alipour et al 9 showed that mini-scleral lenses, with a diameter under 15.8 mm, were effective in the treatment of moderate to severe dry eye. Furthermore, we observed that semi-scleral lenses were effective both objectively (alleviation of punctate epitheliopathy and a reduction in lissamine green staining) and subjectively (improved patient quality of life).…”

We presented a case of refractory dry eye management with semi-scleral contact lens. Dry eye was associated with facial nerve (cranial nerve VII) palsy as a result of cerebellopontine angle tumor surgery. She was treated with several topical treatments and punctal plug. Despite the treatments, her symptoms still persisted. Her ophthalmic examination revealed scleral exposure because of lagophthalmos, conjunctival hyperemia, corneal debris, scar, and diffuse punctate epitheliopathy on her right eye. Lissamine green staining showed diffuse conjunctival and corneal staining. Therapeutic semi-scleral lenses were fitted. The corneal findings were resolved and the quality of patient life was improved with the aid of semi-scleral lens after 3 months.
