What Is the Anterior Chamber?
The cavity between the back of the cornea and the iris and lens in the eyeball is called the anterior chamber.

- The cavity between the back of the cornea and the iris and lens in the eyeball is called the anterior chamber.
- The cavity between the back of the cornea and the iris and lens is called the anterior chamber, and the anterior chamber is filled with colorless liquid, that is, aqueous humor. 98% of the humor is water. The depth of the anterior chamber should be the distance from the posterior vertex of the cornea to the front of the lens in the direction of the optical axis. But sometimes the anterior chamber depth can also include the thickness of the cornea. The anterior chamber depth, excluding corneal thickness, was approximately 3.0 mm. According to the literature, the anterior chamber depth of the Chinese is 2.75 ± 0.03mm.
- From an optical point of view, the anterior chamber depth is important because it affects the overall refractive power of the ocular optical system. Assuming other factors remain the same, a 1mm reduction in anterior chamber depth (such as lens advance) will increase the total refractive power of the eye by 1.4D. A deeper anterior chamber will reduce total refractive power. The influence of anterior chamber depth is particularly important in optical calculations for intraocular lens implantation.
