Methods of obtaining ophthalmic lenses providing the eye with reduced aberrations

Abstract

The present invention discloses methods of obtaining ophthalmic lens capable of reducing the aberrations of the eye comprising the steps of characterizing at least one corneal surface as a mathematical model, calculating the resulting aberrations of said corneal surface(s) by employing said mathematical model, selecting the optical power of the intraocular lens. From this information, an ophthalmic lens is modeled so a wavefront arriving from an optical system comprising said lens and corneal model obtains reduced aberrations in the eye. Also disclosed are ophthalmic lenses as obtained by the methods which are capable reducing aberrations of the eye.

1 . An ophthalmic lens, comprising: 
 an aspheric surface; and    an aberration term based on a lens design in which the aberration term is opposite in sign of, and is capable of compensating for, an average aberration term of a corneal model based on a suitable population;    the suitable population being a group of people who will undergo an ocular surgical procedure.    
   
   
       2 . The ophthalmic lens of  claim 1 , wherein the ocular surgical procedure is a refractive corrective surgery.  
   
   
       3 . The ophthalmic lens of  claim 1 , wherein the ocular surgical procedure is a cataract surgery.  
   
   
       4 . The ophthalmic lens of  claim 1 , wherein the ocular surgical procedure is the implantation of an IOL.  
   
   
       5 . The ophthalmic lens of  claim 1 , wherein the ocular surgical procedure is the implantation of a corneal inlay.  
   
   
       6 . The ophthalmic lens of  claim 1 , wherein the ocular surgical procedure is a refractive corrective surgery.  
   
   
       7 . An ophthalmic lens, comprising: 
 an aspheric surface; and    an aberration term based on a lens design in which the aberration term is opposite in sign of, and is capable of compensating for, an average aberration term of a corneal model based on a suitable population;    the suitable population being a group of people who have undergone corneal surgery.    
   
   
       8 . The ophthalmic lens of  claim 7 , wherein the corneal surgery is laser in situ keratomileusis.  
   
   
       9 . The ophthalmic lens of  claim 7 , wherein the corneal surgery is radial keratotomy.  
   
   
       10 . The ophthalmic lens of  claim 7 , wherein the corneal surgery is photorefractive keratotomy.  
   
   
       11 . An ophthalmic lens, comprising: 
 an aspheric surface; and    an aberration term based on a lens design in which the aberration term is opposite in sign of, and is capable of compensating for, an average aberration term of a corneal model based on a suitable population;    the suitable population being a group of people belonging to a specific age group.    
   
   
       12 . An ophthalmic lens, comprising an aspheric surface having a design that includes an aberration term that is opposite in sign of, and is capable of compensating for, an average aberration term of a corneal model based on a suitable population.  
   
   
       13 . The ophthalmic lens of claims  12 , wherein the suitable population is a group of people who will undergo an ocular surgical procedure.  
   
   
       14 . The ophthalmic lens of claims  12 , wherein the suitable population is a group of people who have undergone corneal surgery.  
   
   
       15 . The ophthalmic lens of claims  12 , wherein the suitable population is a group of people belonging to a specific age group.  
   
   
       16 . The ophthalmic lens of claims  12 , wherein a wavefront arriving from an optical system comprising the model cornea and the lens design obtains a substantially reduced aberration compared to a similar lens design that does not include the aberration term.
