Abstract Details

Purpose:

Cataract surgery in patients with keratoconus can be demanding due to difficulties in selecting the intraocular lens (IOL) and predicting the refractive outcome. We report a case of cataract surgery in a patient with keratoconus and using objective Itrace (Tracey, Houston, Texas) technology.

Setting:

Hospital La Fe, Valencia, Spain

Methods:

We present the case of a 41-year-old man with bilateral cataract and advanced bilateral keratoconus treated with intracorneal rings (ICR) in both eyes (BE). Preoperatively, best corrected visual acuity (BCVA) was 20/150, with − 2.5 sph − 9. cyl 32°, in the right eye and 20/40, with - 1.5 sph − 4,5 cyl 125 in the left eye. The previous measurements were done with Itrace technology using the Previous Toric Check Alignment, the Tracey refraction, the Kappa and Alpha angle and the analysis of the Disfunctional Lens Display.

Results:

The patient was subjected to a correct phacoemulsification with implantation of a toric IOL in BE. BCVA postoperatively was 20/80 with + 1 sph − 3 cyl 65° in the right eye and 20/25 with  + 0.5 sph − 3.5 cyl 613° in the left eye. All the Itrace measurements were done after surgery (Postoperative Toric Check Alignment, Tracey refraction, the Kappa and Alpha angle and analysis of the Disfunctional Lens Display).

Conclusions:

Correction of astigmatism and cataract with phacoemulsification and implantation of a toric IOL in patients with keratoconus can be an effective and safe choice. But predicting the refractive outcome is sometimes difficult. The measurements with the Itrace technology suppose a perfect system for evaluating an improvement of the visual quality of the patient.
