<H4>PURPOSE</H4>
<P>To analyze the results of a custom-designed posterior chamber toric phakic
intraocular lens (PIOL).</P>
<H4>METHODS</H4>
<P>A 40-year-old woman with high astigmatism and thin corneas underwent
bilateral PIOL implantation with the toric Implantable Collamer Lens (ICL)
custom-designed and manufactured by STAAR Surgical. The appropriate toric ICL
power was calculated to be –8.00 +8.00 x 96° for the right eye and
–8.50 +7.50 x 86° for the left eye. Optical zone was 5.5 mm and 6.875
mm at the corneal plane.</P>
<H4>RESULTS</H4>
<P>At 3 and 6 months postoperatively, uncorrected visual acuity (UCVA) and
best-spectacle corrected visual acuity (BSCVA) of both eyes had improved to
20/20 and 20/16, respectively. At 19 months, UCVA was 20/20 and 20/16 in the
right and left eyes, respectively, and BSCVA had improved to 20/16 and 20/10,
respectively. The subjective refraction was stable, with a change of
–0.37±0.17 D from preoperative to 19 months postoperatively.
Throughout the postoperative period, iridotomies remained patent and the
corneas were clear.</P>
<H4>CONCLUSIONS</H4>
<P>Bilateral implantation of the custom-designed toric ICL successfully
corrected the patient’s high astigmatism. Preoperative subjective
refractive cylinder of –5.25 x 6° in the right eye and –5 x
176° in the left eye changed to –0.5 x 77° and –0.5 x
115°, respectively, after toric IOL implantation. There was almost no
change in corneal astigmatism. This customized approach led to UCVA of 20/20 in
the right eye and 20/16 in the left eye, and BSCVA of 20/16 in the right eye
and 20/10 in the left eye. This is the first report of a toric PIOL being
specifically manufactured to meet the refractive cylinder requirements of a
specific patient. [<CITE>J Refract Surg.</CITE> 2008;24:501-506.]</P>
