Abstract Details

Purpose:

To evaluate e�ï�¬�€ectiveness of simultaneous wavefront-guided photorefractive keratectomy and corneal collagen crosslinking in keratoconus.

Setting:

Hankou Aier Hospital, Wuhan, China

Methods:

Prospective nonrandomized interventional study including 13 eyes of 8 patients with grade 1-2 keratoconus that underwent wavefront-guided transPRK using AMARIS (SCHWIND, Germany) followed by accelerated UVA collagen cross-linking(Avedro, USA). Maximum ablation depth did not exceed 70um. Follow-up period: 3-12 months.

Results:

UCVA was significantly improved from 0.85�Â�±0.46 logMAR preoperative, reaching 0.22�Â�±0.18 logMAR at 3 months (P<0.001). Preoperative BCVA (0.53�Â�±0.34 logMAR) showed a improvement to 0.10 �Â�± 0.09 logMAR at 3 months (P<0.001). Mean K value reduced from 45.6 �Â�± 3.89 D to 41.5 �Â�± 3.76 D at 3 months (P<0.002). Mean cylinder decreased from 3.55 �Â�± 0.79 D to 1.25 �Â�± 0.81D (P<0.003).

Conclusions:

Simultaneous wavefront-guided photorefractive keratectomy and accelerated corneal collagen crosslinking is an effective procedure in the treatment of keratoconus.
