Anterior Chamber Depth (ACD) plays an important role in several eye conditions, including inflammatory eye processes, keratoconus, endothelial cell density loss (ECDL), oxidative stress in endothelial cells, glaucoma surgical interventions, phacoemulsification surgery, anterior chamber dimensions, intraocular lens (IOL) formula calculations and surgical post refractive errors.ACD corresponds to the distance between the corneal endothelium to the anterior lens capsule. Some authors may include the corneal thickness (CT) in this term, increasing approximately 0.5mm, corresponding to the average CT in mm. Although this is not a consensus, it is usually specified as ACD-CT [1]. ACD varies with age and gender. It has an inverse proportional relation with age, and directly proportional relation with the anterior chamber angle (ACA), and axial length (AL) [2,3]. Moreover, for every millimeter increase in AL the ACD distance increases by 0.07 mm, and by every year increment in a patient's life the ACD decreases by 0.005mm. This led to the following formulas; estimated ACD [3.339 -0.005(age in years)] and ACD [0.07(axial length in mm)+1.4892] [4]. Other reported rates of ACD shallowing per year have been described, by Xu in the Beijing Eye Study at 9 μm/year [5] Fernandez-Vigo by 10.4 μm/year [6], Rufer 11.5 μm/year [7], Sun by 11.9 μm/year [8] Sng by 15 μm/year [9] and Yan by 17 μm/year [10]. The relevancy of this issue, albeit the immense variations just described, lies in the young individual that receives an IOL. Given their theoretically
