Abstract Details

Purpose:

To evaluate the influence of deep anterior lamellar keratoplasty (DALK) on anterior segment parameters obtained with the Pentacam�Â�® Scheimpflug camera.

Setting:

Ophthalmology Dept., Hospital de Santa Maria, Lisboa, Portugal.

Methods:

Retrospective case-series. Consecutive patients were evaluated preoperatively, and at a minimum 12-month follow-up postoperatively with Pentacam�Â�®. We compared pre- and post-operative measurements of anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA) width, intraocular pressure (IOP) and total corneal refractive power (TCR).

Results:

A total of 10 eyes of 10 consecutive patients (5 male) were included, with a mean age of 36.3 �Â�± 1.5 years. In all but one case advanced keratoconus was the indication for surgery. Mean K reading of the cornea flattened from 54.1 �Â�± 5.1 diopter before DALK to 47.2 �Â�± 2.1 diopter(p=0.02) at last follow-up visit, and best-corrected visual acuity(Snellen) improved from 0.125 �Â�± 0.09 to 0.74 �Â�± 0.23 postoperatively. Mean ACV was lower after follow-up (177 �Â�± 62�Î�¼m) when comparing to preoperative measurements (193 �Â�± 58�Î�¼m, p=0.01). ACD, ACA and IOP did not change significantly following DALK surgery.

Conclusions:

While being an effective option for corneal ectasic disorders, DALK surgery likely causes little influence in the anterior chamber anatomy, and the less dependence on corticosteroids helps to reduce complications related to high IOP during follow-up.
