Comparative analysis of intraocular lens power calculation methods after excimer laser surgery.

Many methods have been used in an attempt to more accurate predict the intraocular lens (IOL) power in the eyes undergoing refractive surgery, but none has proved most accurate. The aim of this study was to evaluate the accuracy and predictability of different IOL power calculation methods in eyes after excimer laser surgery. The outcomes of phacoemulsification and IOL implantation in 18 eyes of 16 patients with prior excimer laser keratectomy were documented.

Ultrasound findings in Terson's syndrome: two case reports.

Terson's syndrome describes the concurrence of intracranial hemorrhage, vitreous hemorrhage and juxtapapillary subinternal limiting membrane and retinal hemorrhage. In most cases, the retinal and vitreous hemorrhage will clear spontaneously. Vitrectomy was indicated by persistent hemorrhage in two cases.
