Abstract
The corneal triple procedure is that penetrating keratoplasty, extracapsular cataract extraction, and posterior chamber intraocular lens implantation are performed simultaneously and preoperative prediction of intraocular lens implant power is necessary to achieve the desired postoperative refractive status in eyes undergoing the triple procedure. Therefore we evaluated the important factors in determining intraocular implant power patients undergoing the triple procedure. A retrospective study was done on 12 eyes of 11 patients who underwent triple procedure between March 1993 and April 1997. Mean age was 52.9 years and mean follow-up period was 26.3 month(range, 4 to 53 months). The Mean postoperative spherical equivalent was -0.98+/-4.05D. Forty-two percents of patients were within +/-2.00D of emmetropia. The important factors in determining intraocular lens power of patients undergoing the triple procedure are axial length, corneal curvature, refractive status of the fellow eye, and donor/recipient size. If these values are unreliable, it is desirable for the corneal srurgeon to use mean axial length and mean corneal curvature to determine the intraocular implant power.
