To evaluate the Visual Acuity improvement obtained with Spot®CSLs after ICRs Surgery for KC.
Patients with KC operated on with ICR
It is a retrospective study of 10 eyes with Keratoconus grade 3 and 4 operated on with ICRs. After surgery, UDVA and CDVA improved but remained limited (> 0.3 LogMar). It is well known that the adaptation of corneal contact lenses is difficult after ICRs. So we have used Spot®CSLs to obtain a better Visual rehabilitation. We describe the adaptation technique and results.
The adaptation is different with Spot®CSLs than with corneal contact lenses, as the goal is to have no contact between the Contact Lens and the cornea, the contact being on the conjunctiva. All our KCs with ICRs eyes has been equipped with Spot CSLs with an impressive Visual improvement (Visual acuity < 0.18 LogMar p <0.001), with less HOAs (p<0.001) and a good tolerance.
ICRs stabilize Keratoconus of stage 2 to 4 and improve Visual acuity by reducing astigmatism and myopia as proved by numerous publications. However, Visual acuity of the patients operated on returns rarely to emmetropia. To improve the refractive result, Topolink Excimer laser with Cross Linking arent always possible as the cornea is too thin. Contact lenses adaptation can be attempted. Toric soft lenses are comfortable but give rarely a good visual acuity. Corneal flexible lenses give good visual acuity outcomes but arent comfortable as they move on the residual corneal surface irregularities. Spot®CSLs dont touch the cornea, dont move and are rigid contact lenses which allow good comfort and considerable improvement of Visual acuity. Spot®CSLs adaptation on Keratoconus after implantation of ICRs is possible and improves refractive results when necessary after ICRs implantation.
