Abstract Details

Purpose:

To evaluate the refractive outcome 16 months after big-bubble Deep Anterior Lamellar Keratoplasty (DALK) in pediatric patients performed using femtosecond laser with mushroom incisions or mechanical trephine.

Setting:

Ophthalmology Department, Bambino Gesł IRCCS Children’s Hospital, Rome, Italy

Methods:

Ten eyes of 10 patients affected by keratoconus were treated. Five eyes (Group 1) underwent big-bubble DALK by Hessburg Barron mechanical trephine (mean age 12?4.0?SD? years; range, 8 to 16 years) and 5 eyes (Group 2) by IntraLase 60 KHz (Abbott Medical Optics, Inc.) femtosecond laser with mushroom incisions. (mean age 14?3.6?SD? years; range, 8 to 10 years). Sutures were removed by 10 postoperative months in all patients. Spherical equivalent, refractive astigmatism and Best Corrected Visual Acuity (BCVA) were evaluated 16 months after surgery. The independent Student t test was used to compare each parameter between the 2 groups (P <0.05 was considered significant).

Results:

In Group 1 spherical equivalent and refractive astigmatism were -4.9?0.7?SD? and -5.8?3.3?SD? , while BCVA was 6.6?0.6?SD? . In Group 2 spherical equivalent and refractive astigmatism were -1.3?0.3?SD? and -2.6?0.7?SD?, while BCVA was 8.6?1.1?SD?. Only the spherical equivalent value showed significant changes between Group 1 and 2 (p<0.05).

Conclusions:

These findings suggest that in pediatric patients the big-bubble DALK assisted by femtosecond laser compared to the mechanical trephine seems to improve the refractive outcome.
