“…On the other hand, there is no improvement in VA when toric K lenses are compared with RGPCLs [ 13 , 17 ], and even the quality of life, measured with the CL impact quality of life (CLIQ), is similar [ 18 ]. It is expected that SCLs improve visual function in KC eyes [ 16 , 19 ], but the challenge is to achieve visual results similar to those provided by RGPCLs.…”

Objectives To describe the past 20 years' correction modalities for keratoconus and their visual outcomes and possible complications. Methods A review of the published literature related to the visual outcomes and possible complications in the context of keratoconus management using nonsurgical procedures for the last 20 years (glasses and contact lenses) was performed. Original articles that reported the outcome of any correction modalities of keratoconus management were reviewed. Results The most nonsurgical procedure used on keratoconus management is the contact lens fitting. Soft contact lenses and soft toric contact lenses, rigid gas-permeable contact lenses, piggyback contact lens system, hybrid contact lenses, and scleral and corneoscleral contact lenses form the contemporary range of available lens types for keratoconus management with contact lenses. All of them try to restore the vision, improve the quality of life, and delay surgical procedures in patients with this disease. Complications are derived from the intolerance of using contact lens, and the use of each depends on keratoconus severity. Conclusions In the context of nonsurgical procedures, the use of contact lenses for the management of keratoconic patients represents a good alternative to restore vision and improve the quality of live in this population.

“…In recent years, there have been significant developments in soft contact lens design for the correction of keratoconus [270,307]. Soft lenses are available in high spherical and toric powers for the correction of myopia and astigmatism in early keratoconus, decentred cones, and for patients with rigid lens intolerance [317,318].…”

Keratoconus is a bilateral and asymmetric disease which results in progressive thinning and steeping of the cornea leading to irregular astigmatism and decreased visual acuity. Traditionally, the condition has been described as a noninflammatory disease; however, more recently it has been associated with ocular inflammation. Keratoconus normally develops in the second and third decades of life and progresses until the fourth decade. The condition affects all ethnicities and both sexes. The prevalence and incidence rates of keratoconus have been estimated to be between 0.2 and 4,790 per 100,000 persons and 1.5 and 25 cases per 100,000 persons/year, respectively, with highest rates typically occurring in 20-to 30-year-olds and Middle Eastern and Asian ethnicities. Progressive stromal thinning, rupture of the anterior limiting membrane, and subsequent ectasia of the central/paracentral cornea are the most commonly observed histopathological findings. A family history of keratoconus, eye rubbing, eczema, asthma, and allergy are risk factors for developing keratoconus. Detecting keratoconus in its earliest stages remains a challenge. Corneal topography is the primary diagnostic tool for keratoconus detection. In incipient cases, however, the use of a single parameter to diagnose keratoconus is insufficient, and in addition to corneal topography, corneal pachymetry and higher order aberration data are now commonly used. Keratoconus severity and progression may be classified based on morphological features and disease evolution, ocular signs, and index-based systems. Keratoconus treatment varies depending on disease severity and progression. Mild cases are typically treated with spectacles, moderate cases with contact lenses, while severe cases that cannot be managed with scleral contact lenses may require corneal surgery. Mild to moderate cases of progressive keratoconus may also be treated surgically, most commonly with corneal crosslinking. This article provides an updated review on the definition, epidemiology, histopathology, aetiology and pathogenesis, clinical features, detection, classification, and management and treatment strategies for keratoconus.

“…Furthermore, high thickness SCL is an alternative option in order to reestablish the symmetry of the optical anterior segment and decrease the HOA. In addition, high thickness SCL improves comfort during its wear and quality of life on irregular corneas [20][21][22][23][24][25][26][27][28][29]. Fernández-Velázquez and Fernández-Fidalgo [29] demonstrated an increase in high-contrast CDVA with high thickness SCL after ICRS implantation, these values being close to normative data.…”

“…In recent years, SCL fitting has proved to be an alternative to RGP lenses on irregular corneas, including ICRS implanted, in order to improve optical and visual quality [17][18][19][20][21][22][23][24][25][26][27][28][29]. SCL are especially recommended in patients who want to increase their comfort, assuming a reduction of visual function compared to RGP wearers [16].…”
