ABSTRACT
PURPOSE: To evaluate the refractive status, axial length, and refractive power of the cornea in pediatric patients after unilateral cataract surgery and intraocular lens implantation. METHODS: Refractive state, refractive power of cornea, and axial length were measured both in the operated and nonoperated eyes in 15 patients (age at surgery = 5 to 15 years; mean, 10.3) before and 4 to 15 years (mean, 9.7) after unilateral cataract surgery. RESULTS: After surgery, visual acuity was 20/40 or better in 79% of operated eyes. Myopic changes, representing the difference between postoperative refraction at last follow-up and postoperative refraction at 1 year after surgery, were noted in the operated eyes at the end of study (mean, -5.02 D), but there were no significant differences in axial length (Wilcoxon signed rank test P >.05) or refractive power of the cornea between operated and nonoperated eyes (paired Student t test P >.05). CONCLUSION: Myopic shift after cataract surgery with intraocular lens implantation may occur even in older children.

We describe a rare case of giant basal cell carcinoma which invaded the orbital tissue and the anterior skull base. Though the eyeball in the right orbit was preserved with the tumour at the patient's request, the improvement in the quality of the patient's life was achieved.

PURPOSE: To evaluate the intraocular power calculation formula for children and the change of the refraction. SUBJECT AND METHODS: We reviewed the medical records of 66 pediatric cases with intraocular lens (IOL) implantation after cataract extraction and results of questionnaire of the Japanese Association of Pediatric Ophthalmology and Japanese Society of Cataract and Refractive Surgery. We employed four IOL power calculation formulae(SRK, SRK II, SRK/T, Holladay) to evaluate the accuracy of preoperative prediction of refraction. RESULTS: The best preoperative prediction was obtained by the SRK formula; the predictive refraction error within +/- 1 D was shown in 65% of patients. SRK/T and Holladay formulas were less accurate in patients aged 5 years old or younger. All formulae were less accurate in patients with axial length of 22 mm or shorter. There was no significant difference in the mean change in refraction over four years among three different age group (group 1: < = 5, group 2: 6 << = 10, group 3: 11 << = 15(years old(YO)). However, several patients aged 10(YO) or younger showed severe myopic changes during this period. CONCLUSION: The IOL power calculation fomulae show less accuracy on pediatric cases. It is also difficult to predict the change of refraction on pediatric cases.
