Abstract Details

Purpose:

to evaluate the efficacy of femtosecond arcuate incision to correct irregular astigmatism in pediatric patients.

Setting:

Bambino Gesù IRCCS Children's Hospital, Rome, Italy

Methods:

two pediatric patients (2 and a 16 years old; patient A and B respectively) underwent arcuate incisions performed by IntraLase 60 KHz femtosecond laser (Abbot Medical Optics). Patient A presented a corneal scar after penetrating trauma with 11 diopters of residual astigmatism, while patient B showed an high post-penetrating keratoplasty refractive error (Corrected Distance Visual Acuity, CDVA, 4/10 with -12sph and -4cyl axis 50° - 0.8 with foramen; intolerance to contact lenses). Pre- and postoperative CDVA, corneal topography and aberrometry were evaluated by Sirius scheimplflug camera (CSO). Follow up is 48 months.

Results:

4 years after surgery and rehabilitation therapy patient A CDVA is 9/10 EU with +1sph and -6 cyl axis 80°, while, after arcuate incision and sequential Phakic IOL implantation, patient B CDVA is 10/10 with +0.50sph. In both patients total aberrations decreased for 3.0 and 5.0mm diameter.

Conclusions:

: In selected pediatric patients new refractive surgical approaches could be evaluated in the attempt to correct high refractive errors and treat amblyogenic astigmatism, also avoiding the need of keratoplasty. FINANCIAL INTEREST: NONE
