Summary:
Retrospective clinical trial evaluated efficacy and safety of phototherapeutic
keratectomy(PTK) within35children(35 eyes) aged8 to 18years (mean12,6years).
All children hada long timepostoperative follow-up rangedfrom2 to5 years (mean
3,2 years).
Indications for PTK in children were: recurrent corneal epithelial erosion syn-
drom, superficial scars after keratitis „e lagophthalmo“, dry spots and mucous
plaques after atopic- vernal eye disease, band keratopathy, anterior corneal
dystrophies, corneal scars secondary to post-infectious keratitis (post-herpes
simplex corneal scarring) and following trauma. The aim of treatment were to
improve visual acuity and to reduce or eliminate subjective ocular discomfort -
pain, lacrimation and photophobia. Fully informed parents consent was done at
all cases.
There was increased the best spectacle corrected visual acuity (BSCVA) in all
children, and episodes of ocular pain, lacrimation and photophobia diminished.
The mean preoperative BSCVA 6/36 (ranged from 6/9 to 1/60) improved to mean
value 6/12 (ranged from 6/6 to 6/60) as 2 - 5 years follow-up postoperatively.
Seven children had 5 or more Snellen’s lines gain of the BSCVA, ten children gained
4 lines, eight children gained 3 lines and five children gained 2 lines postoperatively
in comparison to their preoperative values. At four cases were evaluated only 1 line
gain of BSCVA, one eye unchanged, and no eye had BSCVA worsened after PTK.
Phototerapeutic keratectomy in children seems to be an effective and safety
procedure in the management of suitable anterior corneal disorders. Our clinical results suggest the most suitable diagnoses for treatment include recurrent
corneal epithelial erosions, bandkeratopathy, dry spots, mucous plaques, anterior
corneal dystrophies, and anterior post-keratitis and post-traumatic scars.
