Gliederung

Text

Choosing the right IOL is not always easy. Depending upon patient's demands it might be monophocal or premium IOL. To get target refraction we need to be very precise with investigation/calculation and equipment we use should be tested properly. But there is one more constituent that we cannot investigate and just need to believe it. It is IOL that we get from manufacturer with individual optical power.

We represent a case of cataract surgery with IOL implantation. Prior to the surgery patient was examined routinely and IOL was calculated targeting to emmetropical(IOL +24,5 D) refraction after surgery. After uneventful surgery with endocapsular IOL implantation patient had visual acuity comparable to aphakic (0, 02 +11, 0=0, 8). Sciascopy revealed H +11, 0 and autorefractometry recorded +11, 25 -1, 50 ax 86. IOL Master data: see Table 1 [Tab. 1]).

Refraction remained stable until next surgery.

Six months later IOL was explanted with simultaneous aphakic Artisan IOL (+24, 0 D) implantion into the posterior chamber, right eye. Two months after reimplantation best uncorrected distance visual acuity was 0, 6.

Reason for such unexpected refractive outcome might be: miscalculations with IOL, significant shift of the IOL towards retina creating hyperopic refraction.

On the other hand no one can ignore inaccuracy during IOL production.
