| Popis: | Ultrasonography and keratometry are used in the study of the refraction of the eye. The authors used the artificial implant lens after removal of the cataractous lens. The expected emmetropizing power of the implant lens can be calculated by a formula as well as the expected post-operative refraction which can also be calculated by second and third formulas. The authors compared the difference between the expected pre-operative and actual post-operative refraction. The factors giving this difference will be discussed. The expected emmetropizing power of the implant lens is not always the same as that of the iseikonizing power. A theoretical discussion of this problem is given. |
