Femtosecond laser-assisted in situ keratomileusis for the correction of residual ametropia after deep anterior lamellar keratoplasty: a pilot investigation
No full textPurposeTo evaluate the refractive and visual results of one-stage laser-assisted in situ keratomileusis with femtosecond laser (Femto-LASIK) for the correction of residual ametropia after deep anterior lamellar keratoplasty (DALK).MethodsThis retrospective study included 13 eyes of 12 patients, who underwent corneal Femto-LASIK to correct refractive errors after DALK. IntraLase FS150 was used to create a lamellar flap and excimer laser ablation for refractive correction was performed using the Star S4 IR Excimer Laser in eight cases and the Technolas 217z Excimer Laser in Tissue Saving mode in five cases. Perioperative variables of interest included uncorrected (UDVA) and corrected (CDVA) distance visual acuities, manifest refraction and corneal topography.ResultsThe mean spherical equivalent preoperatively was 4.85±2.82 (range, 9.5 to 0 D). At the last visit the mean postoperative spherical equivalent (SE) was 0.44±0.67 D (P<0.05). The mean postoperative UDVA was 0.12±0.12 logMAR. There was a statistically significant increase in CDVA 6 months after Femto-LASIK (P<0.05). Intraoperative and postoperative complications did not develop in this series of eyes.ConclusionsCorrecting the preoperative manifest refractive error with Femto-LASIK led to a significant improvement in the UDVA and CDVA without surgical complications.

Pleomorphic adenoma of the lacrimal gland in an 18-year-old girl irradiated for bilateral retinoblastoma
No full textPURPOSE:
To report a case of pleomorphic adenoma of the lacrimal gland following irradiation for bilateral retinoblastoma.
MATERIALS AND METHODS:
Case report. A 4-month-old girl, with bilateral retinoblastoma, underwent enucleation of the right eye, systemic chemotherapy and bilateral external beam irradiation with a lateral field. The right anophthalmic socket (because of infiltration of the optic nerve) and the left eye (for relapse) were irradiated;. 17 years later, she developed a mass in the superotemporal quadrant of the left orbit. The mass was completely excised.
RESULTS:
Pleomorphic adenoma is rare in children and teenagers; it usually presents as a painless, slow growing mass in healthy adults. In this case, it developed as a second primary tumor after irradiation for retinoblastoma
