Abstract Details

Purpose:

To evaluate the effect of deep anterior lamellar keratoplasty (DALK) on corneal keratometry and the anterior segment parameters obtained with the Sirius corneal topography.

Setting:

Cornea and Refractive Surgery Department

Methods:

A total of previously diagnosed with 15 keratoconus patient’s 15 eyes (9 men, 6 women, 26.0±6.6) were evaluated preoperatively and 3 months postoperatively with the Sirius corneal topography. (Costruzioni Strumenti Oftalmici, Italy). The preoperative and postoperative measurements of Keratometry (K), anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA) width were recorded.

Results:

Preoperative mean K decreased from 64.72±3.35 to 45.39±4.04 at 3 months after surgery.(p<0.0001) Preoperative and Postoperative values were; for ACD measurements 3.48 ±0.68 mm and 3.46±0.58 mm (p=0.196), for ACV measurements 187.01±22.76 and 186.80±26.15 (p=0.783), ACA measurements 51.6o ±6.90 and 40.61±8.12.(p=0.02)

Conclusions:

DALK significantly decreased the corneal K readings and anterior chamber angle. The stability of the corneal volume and anterior chamber depth was thought to be related with the stability of the anterior chamber after the nonpanetrating surgery. However the decrease on the anterior chamber angle has to be considered on possible secondary surgeries like cataract or glaucoma surgeries and apacic IOL implantations.
