1. A process for preventing or delaying of age-related cataract or the progression of cataract in a patient using a laser apparatus to create ablation points in a crystalline lens of the patient, the process comprising the steps of: selecting a patient having one or more symptoms of cataract or based on one or more increased risk factors for cataract prior to detecting cataract in the patient,ablating epithelial cells in the germinative zone or the pregerminative zone of the crystalline lens of the patient in a fashion that avoids damage to fiber cells. 2. A process for preventing or delaying the progression of cataract by ablating epithelial cells in a crystalline lens using a laser apparatus to create ablation points on a crystalline lens of the patient, the process comprising the step of selecting a patient having one or more symptoms of cataract; andablating epithelial cells in the germinative zone or the pregerminative zone of the crystalline lens of the patient without ablating fiber cells. 3. The process of claim 2, wherein the patient has one or more symptoms of age-related cataract, and the process prevents or delays progression of age-related cataract in the patient. 4. The process of claim 2, wherein ablation points are made in the germinative zone of the crystalline lens. 5. The process of claim 2, wherein ablation points are made in the pregerminative zone of the crystalline lens. 6. The process of claim 2, wherein the epithelial cells are ablated symmetrically. 7. The process of claim 2, wherein the epithelial cells are ablated along suture lines of the crystalline lens. 8. The process of claim 2, wherein the crystalline lens has a circumference, and the process comprises making ablation points symmetrically around essentially the entire circumference. 9. The process of claim 2, wherein at least about 10% of the epithelial cells in the germinative zone of the crystalline lens are ablated. 10. The process of claim 2, wherein the laser apparatus generates a plurality of laser beams, and the plurality of laser beams from the laser apparatus is provided to the crystalline lens of the patient to create a pattern of ablation points on the crystalline lens of the patient. 11. A process for preventing or delaying of age-related cataract in a patient using a laser apparatus to create ablation points on a crystalline lens of the patient, the process comprising the steps of: selecting a patient based on one or more increased risk factors for cataract prior to detecting cataract in the patient, andablating epithelial cells in the germinative zone or the pregerminative zone of the crystalline lens of the patient without ablating fiber cells. 12. The process of claim 11, wherein the patient is selected based on one or more increased risk factors for age-related cataract. 13. The process of claim 11, wherein the patient is selected based on age. 14. The process of claim 11, wherein the patient is selected based on a genetic predisposition to cataract as one of the increased risk factors for cataract. 15. The process of claim 11, wherein the patient is selected based on personal or family history of cataract as one of the increased risk factors for cataract. 16. The process of claim 11, wherein the patient is selected based on previous eye surgery as one of the increased risk factors for cataract. 17. The process of claim 11, wherein the increased risk factor for cataract is a systemic disease. 18. The process of claim 17, wherein the systemic disease is diabetes. 19. The process of claim 11, wherein the laser apparatus generates a plurality of laser beams, and the plurality of laser beams from the laser apparatus is provided to the crystalline lens of the patient to create a pattern of ablation points on the crystalline lens of the patient.
