Conditions

cataract

Interventions

Group 1: Arm 1: Patients over 40 years of age with cataract, who will undergo surgery and implantation of a monofocal intraocular lens.

Eligibility

Sex/Gender
All
Age
40 Years to No maximum

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

MeasureTime 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

MeasureTime frame
To assess the differences between eyes with short axial length (less than 22.1 mm) and long axial length (greater than 25 mm).
