Brief Summary
Measuring parameters of anterior segment of the eye accurately is important for diagnosing variety of diseases and for cataract surgeries, glaucoma, refractive surgeries and post-operative follow-up. One of the anterior segment parameters is the anterior chamber depth. The anterior chamber depth (ACD) measurement provides valuable information in different fields in ophthalmology. Firstly, it is important for the new theoretical biometric formulas used to calculate the power of intraocular lenses (IOLs) .Secondly, phakic IOL implantation requires precise ACD measurement for both surgical planning and IOL power calculation. Thirdly, the ACD is also implicated as a screening risk factor for glaucoma. Additionally, precise ACD measurement is thought to be important to the accurate determination of the optic zone ablation diameter for keratorefractive surgery, as well as for the analysis of postoperative ACD changes. Different technologies are used in measurement of the anterior chamber depth Such as pentacam and iol maste

Outcome Measures
Primary Outcomes (1)
Comparison between values of anterior chamber depth obtained by different devices
Measuring Anterior chamber depth by Pentacam and iol master in eyes with different refractive errors
One year
Study Arms (3)
Myopic patients
Hypermetropic patients
Emmetropic people
Interventions
Iol master measures the distance between anterior pole of the cornea and the anterior surface of the lens to calculate the anterior chamber depth
The Pentacam HR calculates Anterior chamber depth from the corneal endothelial layer along a line from the apex of the cornea to the anterior surface of the lens
