Abstract
Purpose::
To investigate the long-term outcome of eyes after implantation of a newly developed intraocular lens (PC/IOL) with reversibly adjustable refractive power (*Acri.Tec AR-1 PC/IOL).
Methods::
Continued observation of the initial 35 human eyes into which the *Acri.Tec AR-1 PC/IOL has been implanted. 33 patients have a conventional PC/IOL in their second eye (control group). The cohort consisted of 16 males and 19 females, median age: 76 years (range 61 - 90 years). The control findings include: centration of the IOL, integrity of the posterior lens capsule, central visual acuity, morphology of the eye, intraocular pressure (IOP), refraction of the eye
Results::
Median follow-up was 18 (range 6 to 31 months). Throughout the entire period of observation all eyes were behaving clinically in the same way as if implanted with a conventionel PC/IOL. 2 eyes were adjusted surgically 2 weeks after implantation. 18 eyes underwent Nd:YAG laser capsulotomy after a median period of 12 (range 6 to 21) months after implantation. Median change of spherical equivalent between 1 month and the last visit was 0 (range - 0.5 to + 0.5) diopters. At the last visit median best visual acuity was 0.7 (range 0.2 to 1.0) for eyes with the adjustable PC/IOL and 0.8( range 0.3 to 1.0) for eyes in the control group.
Conclusions::
The data suggest that a mechanically adjustable PC/IOL is a safe implant. It gives stable refractions after implantation, Nd:Yag laser capsulotomy and adjustment surgery. A mechnically adjustable PC/IOL can be used in human eyes to adjust the refraction of pseudophakic eyes to the desired value.
