Abstract Details

Purpose:

Study the cause of intermittent bilateral rotation after implantation of bilateral spherical ICL with normal vault .

Setting:

: Clinica Baviera. Instituto oftalmológico Europeo. Málaga, Spain

Methods:

We implanted two ICL with a period of 15 days between the right eye and left in a male patient 35 years old . Preoperative Refraction: Right eye -11.75 -0,5 175 º and -12.25 -0.75 160 º for the left one. We used Orbscan II scanning-slit corneal topographer and microscope calibration for the measuremets of White -to-White (WTW) horizontal distance, and in both eyes it was 12.5 mm . YAG laser iridotomy were performed prior to the surgeries in both eyes . In both eyes we implanted a 13,2 mm horizontal diamater spheric ICL. 15 days after the surgery vault was II in both eyes . One month after the surgery the patient presents intermittent monocular diplopia in both eyes. In the exploration both phakic lens are displaced . We studied the possible subluxation and the explant of the rigth lens but in a new exploration ICL spontaneously turns 90º so we decide the replacement for a big one with 13,7 mm diameter .

Results:

After one week the bilateral monocular diplopia continues so we made an ultrasound biomicroscopy ( BMU ) for the sulcus-to sulcus horizontal distance (STS) .The STS is 14.49 mm for the right eye and 14.29 mm for the left one. We opted for the explant of both lens , performing surgery without complications.

Conclusions:

It is well known that not in all eyes STS horizontally distance correlates with WTW horizontally measuremets. In the present case the horizontally STS distance with BMU , have made us decide implantate an anterior chamber phakic lens , because actually there isn´t available ICL with more than 13,7mm of horizontal distance.
