Eligibility
Inclusion criteria
Inclusion criteria: - are willing and able to attend all study visits; - be over 40 years of age, regardless of sex or race; - have good ocular health, without any pathology that compromises visual acuity (VA, with the exception of residual refractive error). - patients with indication for monofocal lens implantation. - Eyes with an axial length of less than 22.1 mm (short eye). - Eyes with an axial length greater than 25 mm (long eye).
Exclusion criteria
Exclusion criteria: - corneal opacity; - previous radial keratotomy or other corneal surgery in addition to LASIK or PRK (e.g., corneal transplantation, DSAEK, lamellar keratoplasty). In these cases, a degree of freedom is added to the imprecision of the lens power calculation, adding bias to the study. They are therefore excluded from the study. - previous anterior or posterior chamber surgery; - vitrectomy; - Laser iridotomy; - diabetic retinopathy; - history of retinal detachment; - subjects who have an acute or chronic disease that confounds the results of this investigation (e.g., immunocompromised, connective tissue disease, clinically significant atopic disease, diabetes, or any other similar disease); - keratoconus; - amblyopia and/or strabismus. - Pregnancy. Pregnancy has a known effect on refractive stability and VA so pregnant women are excluded.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Collect clinical refractive data using the ORA VLynk intraocular lens power calculation system and compare with theoretical intraocular lens power calculations using ocular biometry with a commercial IOLMaster 700 biometer (Carl Zeiss Meditec, CE marked) in short (less than 22.1 mm) and long (greater than 25 mm) axial length eyes with implantation of a commercial monofocal lens. | — |
Secondary
| Measure | Time frame |
|---|---|
| To assess the differences between eyes with short axial length (less than 22.1 mm) and long axial length (greater than 25 mm). | — |
