Abstract Details

Purpose:

To evaluate changes in corneal optical densitometry after laser excimer surgery (photorefractive keratectomy) using a Scheimpflug topograph (Pentacam HR, Oculus Gmbh, Wetzlar, Germany).

Setting:

Hôpital d’Instruction des Armées, Laveran, Marseille, France

Methods:

Corneal densitometry (0 to 100 gray scale), pachymetry and keratometry were evaluated with a rotating Scheimpflug camera at baseline, 1 months and 3 months after PRK in myopic patients. Subjective refraction, uncorrected distance visual acuity, best-corrected distance visual acuity and corneal haze (0 to 4 common subjective scale) were evaluated preoperatively at baseline,1 months and 3 months.

Results:

53 eyes (27 right, 26 left) were included between April and November 2013. Preoperative mean spherical equivalent (SE) and cylinder were -2.23 ± 1.38 D and 0.86 ± 0.51 D respectively. Mean preoperative corneal thickness was 545 ± 35 μm, mean preoperative keratometry was 43,31 ± 1,46 D. Maximal corneal densitometry (3 central mm) was 27.66 ± 2.02 at baseline. At 1 month, we observed a corneal haze with a mean clinical grade of 0.8 (p<0.0001) associated with an increased corneal densitometry to 29,08 ± 4,40 (p>0,05). At 3 months, mean clinical haze decreased to 0.6 (p=0.008) and was associated to a significant decrease (p<0.0001) of maximal densitometry (25,57 ± 3,77).

Conclusions:

Corneal densitometry could became an objective value to help rating and following of refractive surgery.
