Scleral lenses: Mexican experience
Statement of the Problem:
Keratoconus is a progressive and idiopathic disease in which the cornea develops into an irregular
and conic shape. The clinical signs include thinning of the cornea in its central or paracentral region, an apical protrusion
that results an irregular astigmatism, and this condition can progress. Keratoconus is the most common form of dystrophy
or corneal ectasia, with an incidence of 50–230 per 100,000 persons. In Mexico, the research on keratoconus is scarce; the
articles published show statistics that are similar to those in international literature, which indicates a higher prevalence in
male patients with a mean age of 24.5 years. The incidence is about 1/2000 people in the general population in Mexico. Medical
management with scleral lenses is a viable treatment for vision rehabilitation.
Methodology & Theoretical Orientation:
Retrospective, cross-sectional, observational, descriptive study of 66 patients with
diagnosis of keratoconus and other secondary ectasias post refractive surgery was done; and for those who were followed from
2014, we are fitting them with scleral contact lenses.
Findings:
We have found two particular situations in patients fitted with scleral lenses in Mexico: in 80% of cases a significant
impingement occurs in the scleral area with lens diameter of 15.8 mm and above, and due to this, peripheral areas need proper
for better alignment of the edge with the sclera or smaller diameters. The other situation is that in 34% of cases the adjustments
to the front surface due to the presence of residual astigmatism resolving this situation with toric designs have been made.
Conclusion & Significance:
Scleral lenses provide excellent vision correction and superior comfort compared to traditional
contact lens options for the management of keratoconus and other ectasias post refractive surgery. In most of cases scleral
lenses provide a really visual rehabilitation. Scleral lens should be considered before surgical intervention. However, lens
designs should be improved especially in the landing zone.
