Condition(s) targeted: Cataract
Intervention: motivation (Behavioral)
Phase: N/A
Status: Completed
Sponsored by: Medical University of Vienna
Summary
Purpose:
The aim of this study was to compare the effect of ciliary body training as proposed by
manufacturers of accommodating IOLs and patient motivation on the pseudoaccommodative
ability with a standard intraocular lens (SA60AT).
Setting:
Department of Ophthalmology, Medical University of Vienna.
Methods:
This randomized, controlled, examiner-masked study comprised 80 eyes of 40 patients that
underwent standard cataract surgery. Patients were randomly assigned to a "motivated" or
"non-motivated" (control) group. In the motivated group, subjects were told to take part in
a special protocol to improve their near-reading ability after cataract surgery and were
instructed not to use near adds for at least 3 months. Follow-up examinations included
best-corrected distance visual acuity (VA), distance-corrected near VA, best-corrected near
VA, defocus curve and reading speed, as well as pilocarpine-, cyclopentolate- and
nearpoint-induced IOL shift assessed with partial coherence interferometry.
Clinical Details
Study design: Allocation: Randomized, Intervention Model: Parallel Assignment, Primary Purpose: Treatment
Primary outcome: visual acuity (best-corrected distance VA, distance-corrected near VA, best-corrected near VA)
Secondary outcome: IOL shift (pilocarpine-, cyclopentolate- and nearpoint-induced) assessed with partial coherence interferometry
Eligibility
Minimum age: 50 Years.
Maximum age: 75 Years.
Gender(s): Both.
Criteria:
Inclusion Criteria:
- Patients suffering from age-related cataract who are enrolled for cataract surgery.
- Age 50 to 75 years
- < 1 D of corneal astigmatism, estimated postoperative VA of 20/30 or better and IOL
power between 16 and 27 dpt
Exclusion Criteria:

period, significant other ophthalmic diseases such as glaucoma, diabetic retinopathy,
etc., or ophthalmic surgery other than cataract surgery
