Background
The aim was to evaluate the clinical results of fitting MSD miniscleral contact lenses (MSD; Happy Vision Corp, Anyang, Korea) in Korean patients with keratoconus.
Methods
This report presents a retrospective case review of 38 keratoconic patients fitted with MSD lenses. Visual acuity, comfort, mean wear time, final lens parameters, relationships between sagittal depth and topographic indices, success rate with the first lens ordered and adverse events were documented.
Results
The mean logMAR visual acuity was improved from 0.85 ± 0.78 with glasses and 0.28 ± 0.29 with corneal rigid gas-permeable lenses to 0.10 ± 0.11 with miniscleral contact lenses. Ninety-seven per cent of patients found the miniscleral contact lenses to be comfortable and the mean daily wear time was 10.1 ± 2.3 hours. The mean sagittal depth was 4.70 ± 0.35 mm and there was no correlation between sagittal depth and topographic indices. An average of 3.4 trial lenses was needed to decide the ordered lens and 1.3 ordered lenses to achieve the optimal fitting. One patient discontinued the wear of the lenses after three months due to discomfort.
Conclusion
The use of MSD miniscleral contact lenses is a good alternative for patients with keratoconus and for those who failed to respond to other types of lens rehabilitation that results in both successful visual outcome and comfort.
Abstract Scleral contact lenses (ScCL) have gained renewed interest during the last decade. Originally, they were primarily used for severely compromised eyes. Corneal ectasia and exposure conditions were the primary indications. However, the indication range of ScCL in contact lens practices seems to be expanding, and it now increasingly includes less severe and even non-compromised eyes, too. All lenses that partly or entirely rest on the sclera are included under the name ScCL in this paper; ...
a b s t r a c t Purpose: To evaluate the success rate of highly gas permeable scleral contact lenses (SCL) for visual rehabilitation after penetrating keratoplasty (PK), over a period of up to 9 years. Methods: A total database of 31 consecutive patient fitted with SCL between January 2004 and December 2009 was retrospectively reviewed. Demographic data, etiology prior to lens fitting, visual outcomes, follow up time and complications were analyzed. Results: All eyes were fitted due to inadequat...

Purpose:To evaluate the Doheny Eye Institute Experience with Prosthetic Replacement of the Ocular Surface Ecosystem (PROSE) scleral lenses for the management of irregular corneas with outcomes based on visual acuity (VA) and visual function.Methods:A retrospective chart review of 58 subjects (90 eye
PURPOSE: Scleral contact lenses are used to treat symptoms of severe dry eyes. Procedures for fitting scleral lenses have been vague because of lack of standardized guidelines. This retrospective case series sought to establish average vault over central cornea in successful scleral lens wearers with dry eyes. METHODS: Anterior segment optical coherence tomography was used to measure the distance between the posterior lens surface and cornea in 20 eyes of 12 consecutive patients successfully fit...
Objectives To evaluate the utility of the Rose K2 XL semi-scleral contact lens (Menicon Co. Ltd., Nagoya, Japan) in the management of the irregular cornea. Methods Twenty-seven subjects (34 eyes) with irregular corneas referred for contact lens fitting were evaluated. A diagnostic trial set was used in the fitting process. Once the trial lens was considered optimal, a final lens was ordered from the manufacturer with the necessary changes in power, edge lift and diameter. We analyzed visual acui...
Abstract Objective To evaluate fitting feasibility and efficacy of mini scleral contact lenses in moderate to severe dry eye patients. Methods Prospective interventional case series, this study included those patients with grades III and IV dry eye disease, whose symptoms could not be controlled by conventional treatments. Demographic data, UCVA, BSCVA were evaluated before fitting. Mini scleral lens fit was assessed by single experienced practitioner and best corrected vision with mini scleral ...
Purpose:The aim of this study was to evaluate both the indications for and results of fitting the Jupiter Scleral Lens in patients with corneal abnormalities.Method:This was a retrospective case review of 63 patients (107 eyes) fitted with scleral lenses between October 2009 and March 2011 at the UC
Keratoconus is a bilateral degenerative disease characterized by a non-inflammatory, progressive central corneal ectasia (typically asymmetric) and decreased vision. In its early stages it may be managed with spectacles and soft contact lenses but more commonly it is managed with rigid contact lenses. In advanced stages, when contact lenses can no longer be fit, have become intolerable, or corneal damage is severe, a penetrating keratoplasty is commonly performed. Alternative surgical techniques...
Objectives: To determine whether parameters of anterior corneal contour as identified by topographic analysis (steep and flat simulated keratometry, reference sphere) predict the base curve of Jupiter scleral lenses in patients with dry eye syndrome and keratoconus. Methods: We identified 33 eyes with dry eye syndrome and 21 eyes with keratoconus that were fit with Jupiter scleral lenses of standard design between June 2006 and July 2009. Steep and flat simulated keratometry powers and shape fac...

Abstract The medical use of contact lenses is a solution for many complex ocular conditions, including high refractive error, irregular astigmatism, primary and secondary corneal ectasia, disfiguring disease, and ocular surface disease. The development of highly oxygen permeable soft and rigid materials has extended the suitability of contact lenses for such applications. There is consistent evidence that bandage soft contact lenses, particularly silicone hydrogel lenses, improve epithelial heal...

This prospective study enrolled intractable ocular surface diseases subjects with uncorrected visual acuity > counting finger but ≥ 0.3 logMAR and best-corrected visual acuity (BCVA) ≥ 0.3 logMAR, to fit large diameter scleral lenses for 12 weeks. 21 eyes (13 subjects) consisting ten eyes (47.6%) with persistent epithelial defects, 6 (28.6...
Purpose To evaluate the visual acuity level achieved by scleral contact lens (CL) fitting in patients affected by keratoconus and to evaluate possible intraocular pressure (IOP) changes during the scleral CL wear using a transpalpebral tonometer. Methods In a prospective case series a comparison was made between visual acuity obtained with glasses, RGP and 16.8mm diameter scleral CL in 30 consecutive patients affected by keratoconus. IOP was tested during scleral CL wear by transpalpebral Diaton...

SIGNIFICANCE Fitting specialty contact lenses (hybrid and miniscleral) can be a useful option in keratoconus patients to decrease higher-order aberrations (HOAs) and increase the quality of vision. PURPOSE The aim of the present study was to compare corneal HOAs between miniscleral and hybrid lenses in keratoconus patients. METHODS The target population of this study was 37 patients with bilateral keratoconus aged 20 to 35 years who were referred to a specialized contact lens clinic by a corneal...
Our aim is to review current and significant articles on contact lens wear in keratoconus patients. A comprehensive literature search of PubMed was performed for the following topics on contact lens wear in keratoconus patients: (1) characteristics of contact lens wearers, (2) safety and efficacy, (3) complications, (4) fitting techniques, (5) contact lens wear after procedures/surgeries, (6) patient satisfaction. A total of 104 studies were finally selected and reviewed. Gas permeable (GP) lens...

Abstract Research and reviews have resulted in clear indications for scleral lens (SL) wear. Those indications include visual rehabilitation; therapeutic use in managing ocular surface diseases, lid and orbit disorders; and refractive correction to enhance visual quality, comfort and quality of life. In some cases, the use of SLs may be contraindicated: the presence of low endothelial cell density; Fuchs’ endothelial corneal dystrophy; glaucoma (because of the risk of an increase in intraocular ...
Scleral contact lenses have always been considered suitable for the correction of irregular astigmatism in keratoconus, as they are able to neutralize irregularities with the tear film meniscus that form with the cornea, while maintaining high levels of comfort. Most of clinical studies on scleral contact lenses in keratoconus report a significant improvement of visual acuity, although this improvement is more limited in advanced keratoconus. The follow-up of all these clinical studies is short ...
