Biometric Characteristics of the Eye With Microcornea/Microphthalmia and Congenital Cataract Before And After Cataract Extraction

Eyes with congenital cataract have usually small cornea due to developmental delay of the globe. Recognition of microcornea/microphthalmia may be important as a potential contributor to the development of aphakic glaucoma after cataract surgery. Biometrics characteristics of eyes with m/m before and after removal of the cataractous lens can justify the occurrence of postoperative complications, including glaucoma. Aim of the study: to report on the changes in the anterior segment biometric characteristics after cataract extraction in eyes with microcornea/microphthalmia with congenital cataract. Methods: The study will be a prospective cohorte. Biometry of eligible eyes with congenital cataract in one or both eyes with horizontal cornea diameter less than 11mm and/or axial length less than 2standard deviation for age will be compare to otherwise normal eyes with congenital cataract before and after cataract extraction. The anterior segment biometric characteristics using ultrasound biomicroscopy to measure anterior chamber depth and angle.Cataract surgery will be conducted with or without intraocular lens implantation.Postoperative follow up will be scheduled at the first week and first month, third and sixth months
