Cataracts

What is a cataract?

When the natural lens inside your eye starts to lose it's clarity, we call it a cataract.  The natural lens resides behind your pupil, and you see through it to view the world.  This lens can also flex and change shape to help you focus over a wide range of distances.  As part of the normal aging process, this lens begins to harden and gradual lose it's transparency.  As it becomes less clear to see through, your vision starts to worsen.  External glasses, contact lenses, or laser refractive surgery cannot help this condition because you would still be trying to see through a cloudy internal lens.  When the natural lens becomes too cloudy to see through and the patient becomes dissatisfied with their vision, cataract surgery is recommended.

 

What is cataract surgery?

Cataract surgery entails the surgical removal of the cloudy natural lens, and replacing it with an artificial plastic intraocular lens (IOL).  Measurements are taken in the office preoperatively so that the proper lens implant power may be calculated.  This allows the majority of your glasses prescription to be compensated for by the IOL resulting in less dependency on glasses afterwards and a markedly reduced prescription for most patients.  Dr. Mitchell and Dr. Morin use an ultrasmall incision, no-stitch, no-patch technique that allows their patients the ability to recover rapidly from the procedure.  Cataract surgery is an brief outpatient procedure with very little restrictions afterwards during the first week.

Intraocular Lens Implant


Intraocular lens implants are essential in the visual rehabilitation of the eye.  In the earlier days of cataract surgery, no artificial lens was used to replace the natural cataractous lens after it was removed.  This required patients to wear the very thick cataract glasses or a high powered contact lens in order to see anything other than large shapes.  The intraocular lens implant that we routinely use in modern surgery allows us to put the majority of your prescription in the artificial lens, so that your new glasses prescription is very thin, and lightweight.  Occasionally, some patients find that they have little or no dependency on glasses after the procedure.  Each patient has their own unique situation, and we aim for customizing the surgery to suit each individual's desires and circumstances.

Lens Options

Several intraocular lens implant choices are available and Dr. Mitchell & Dr. Morin will help you decide which one is best suited for you.  Current lenses include the standard monofocal lens, astigmatic monofocal lens, and multifocal lens.
