Into our practice came a 20 years old patient to discuss her possibilities for refraction surgery. She
has been wearing glasses since she was 7 years old and in her eye anamnesis she did not report any
injuries or operations. Strabismus or amblyopia neither. However, she mentioned that on the eye
chart, was never able to read line 1,0 (during examination binocular CDVA was 0,63) and she
reports instability of her refractive error.
Her dominant eye was left. After measuring both corneas on pentacam, we got refractive powers
higher than 50 dioptre, which means that laser refractive surgery wasn ́t indicated. Suggested
options were to try RGP lenses or possibility of implantation of phakic toric intraocular lenses in
Our patient decided on conservative procedure and binocular CDVA 1,0 was reached after RGP
Based on this case study we can see that RGP contact lenses are possible solutions in cases where
glasses aren’t providing required visual acuity and laser refractive surgery is not indicated.
Do you limit the daily time RGP lenses are worn on the eye? How often does the patient need to exchange the RGP lens?
