Correcting Common Eye Conditions with Cataract Surgery

Like cataracts, astigmatism and presbyopia are common eye conditions that tend to develop and worsen with age. As such, many people who have cataracts also suffer from astigmatism and/or presbyopia. When cataract surgery addresses only cataracts, patients with astigmatism or presbyopia will still rely on glasses or contacts to see clearly. At Beach Eye Medical, we offer custom cataract surgery to address astigmatism and/or presbyopia during cataract surgery. Patients who opt to have custom cataract surgery often see better than they did before cataracts developed and are far less reliant upon prescription lenses to see clearly in all situations.

Astigmatism & Presbyopia Overview

Astigmatism is a visual condition that occurs when there is an imperfection in the curvature of the cornea (the clear part of the eye that covers the pupil and the iris). An astigmatic cornea is shaped more like a football than a beach ball. When the cornea is unevenly curved, light does not focus sharply on the retina, causing blurry vision for objects at all ranges of vision.

Presbyopia, the inability to focus on objects in the near range of vision, is a condition that affects most people over the age of 40. Individuals with presbyopia usually wear bifocals, trifocals, or reading glasses to allow them to perform near distance tasks, such as reading a book or using the computer.

Custom Cataract Surgery Corrects Astigmatism & Presbyopia

Beach Eye Medical Group is the exclusive provider of the C.L.E.A.R.® (Custom Lens Exchange and Astigmatism Revision) Upgrade in Southern California. This service provides additional testing before, during, and after cataract surgery, which allows our eye surgeons to customize your surgery so that it addresses common eye conditions like astigmatism and presbyopia. The C.L.E.A.R.® Upgrade may also include the implantation of advanced intraocular lenses, rather than traditional mono-focal lenses, which cannot correct astigmatism or presbyopia.

The Custom Cataract Surgery Process

Custom cataract surgery generally follows the same process as traditional or laser cataract surgery, but with a few variations.

  1. The patient is prepped for surgery. Numbing eye drops are administered and a speculum is positioned to hold the eye open during surgery.
  2. A corneal incision is made to provide the surgeon with access to the lens capsule.
  3. A capsulotomy is performed. This involves making a tiny hole in the front section of the capsule that holds the lens.
  4. The lens is broken into tiny fragments using ultrasound or laser energy. The fragments are then gently suctioned out of the capsule.
  5. The chosen IOL is implanted. In custom cataract surgery, this is typically a premium multifocal lens (to correct presbyopia) or a Toric lens (to correct astigmatism).
  6. In certain cases, the surgeon may also decide to make limbic relaxation incisions to correct higher degrees of astigmatism. These may be performed at the same time as cataract surgery or at a later date.
  7. During the surgery with the CLEAR® Upgrade, our surgeons use Wavefront Aberrometry technology to take precise measurements of the eye. This allows them to make real time adjustments during surgery to achieve an optimal result.
Astigmatism Presbyopia
Recommended IOL Toric lenses Multifocal IOL or Accommodating IOL
Revisions during surgery Limbal relaxation incisions may be made alone or combined with implantation of Toric lenses No additional revisions required
Glasses after surgery? Reading glasses may still be required Many patients will no longer require prescription lenses

If you suffer from cataracts along with astigmatism and/or presbyopia, custom cataract surgery is the best way to improve your vision. If you suffer from any of these conditions, we encourage you to consult with our experienced team of eye doctors to learn more about Custom Cataract Surgery and the CLEAR® Upgrade.
