•* The patient wishes the refractive correction of hyperopia
•* No previouse refractive surgery
•* Contact lens wearers must have removed the hard contact lenses at least 4 weeks and the soft contact lenses at least 2 weeks before the examination
•* Refractive errors: subjective hyperopia up to +6D, subjective astigmatism up to 5D, spherical equivalent (SEQ) up to +8D
•* Best corrected visual acuity 0.8 (in US notation 20/25) or better on both eyes

•* Participation in other ophthalmic studies
•* Pregnant or nursing women, and women planning to become pregnant during the study
•* Existing corneal implants
•* Unstable refraction (over the last 2 years)
•* Immunocompromised patients (e.g. AIDS or autoimmune diseases)
•* Treatment with medications likely to affect wound healing such as steroids, antimetabolite or immunosuppressant
•* Diagnosis of connective tissue disease or diabetes
•* Any residual, recurrent or active disease of the eye (e.g. cataract; glaucoma suspect; corneal diseases; corneal thinning disorders such as keratoconus, pellucid marginal degeneration; dystrophy of basement membrane; exsudative macula degeneration; infections and inflammation of the eye) or of the cornea (e.g. corneal lesion or scarring; herpes simplex or herpes zoster keratitis)
