Outcome Measures
Primary Outcomes (5)
Binocular uncorrected distant visual acuity [bUD-VA]
bUD-VA is obtained using the Greek version of the Early Treatment Diabetic Retinopathy Study Chart at four meters distance. This parameter is obtained six months following the operation of the second eye.
through study completion, an average of 2.5years
Binocular uncorrected intermediate reading acuity (at 60cm) [bUI-RA)]
bUI-RA is obtained using the DDART reading test, which is based on the Greek version of MNREAD. This parameter is obtained six months following the operation of the second eye.
through study completion, an average of 2.5years
binocular uncorrected near reading acuity (at 40cm) [bUN-RA]
bUN-RA is obtained using the DDART reading test, which is based on the Greek version of MNREAD. This parameter is obtained six months following the operation of the second eye.
through study completion, an average of 2.5years
binocular uncorrected intermediate critical print size (at 60cm) [bUI-CPS]
bUI-CPS is obtained using the DDART reading test, which is based on the Greek version of MNREAD. This parameter is obtained six months following the operation of the second eye.
through study completion, an average of 2.5years
binocular uncorrected near critical print size (at 40cm )[bUN-CPS]
bUN-CPS is obtained using the DDART reading test, which is based on the Greek version of MNREAD. This parameter is obtained six months following the operation of the second eye.
through study completion, an average of 2.5years
Secondary Outcomes (4)
Dysphotopsia symptoms
through study completion, an average of 2.5years
Contrast sensitivity
through study completion, an average of 2.5years
Spectacle independence
through study completion, an average of 2.5years
Subjective satisfaction using Visual Function Index (VF-14 instrument) (total score, VF14-NV score & VF14-DV score)
through study completion, an average of 2.5years
Study Arms (4)
Bilateral trifocal implantation
Bilateral implantation of trifocal diffractive intraocular lenses (Panoptix, Alcon) targeting emmetropia
Myopic monovision
The dominant eye defocus is targeted to -0.50 diopters while the recessive one to -1.25 diopters with bilateral implantation of monofocal intraocular lenses (SN60WF, Alcon)
Hybrid monovision
Hybrid monovision combines a monofocal intraocular (SN60WF, Alcon) in the dominant eye and a trifocal diffractive intraocular lens (Panoptix, Alcon) in the recessive one
Premium monovision
Participants received a bifocal hybrid (refractive at the centre, diffractive at the periphery) intraocular lens (Restor +2.50 diopters, Alcon) in the dominant eye and a trifocal diffractive intraocular lens (Panoptix, Alcon) in the recessive one, targeting emmetropia in both eyes.
Interventions
The following clinical indexes are evaluated: 1. Binocular uncorrected distant visual acuity (bUD-VA) using the Greek version of the Early Treatment Diabetic Retinopathy Study Chart at four meters distance 2. Binocular uncorrected reading acuity at 60cm (bUI-RA) and at 40cm (bUN-RA), and 3. Binocular uncorrected critical print size at 60cm (bUI-CPS) and at 40cm (bUN-CPS). All near and intermediate vision parameters are obtained using the Democritus Digital Acuity Reading Test (DDART), which is based on the Greek version of MNREAD. Contrast sensitivity are evaluated with the Pelli-Robson test.
