Exclusion Criteria:
Auto refractometer without cycloplegia Uncorrected visual acuity (logMAR conversion). Anterior segment slit lamp examination UBM examination settings :Supine decubitus position.5150 Vumax (Sonomed, USA) under standard illumination Parameters that will be measured: corneal thickness, anterior chamber depth, angle to angle distance, cornea-posterior capsular lens distance, lens thickness, pupillary diameter, angle of anterior champer and trabecular-ciliary process distance. Cycloplegic refraction UBM examination will be repeated after cycloplegia with the same settings. The patients found to have spasm of accommodation will be subjected to ways to relief the spasm of accommodation and repetition of UBM if possible
