Cataract Surgery Specialist

Eduardo Besser, MD

Ophthalmologist & Eye Surgeon located in Culver City, CA

An estimated 16% of Americans aged 40 and older have cataracts, so it’s comforting to know that cataract surgery has an overall success rate of 97% or higher. Eduardo Besser, MD, specializes in femtosecond laser-assisted cataract surgery and can implant a new intraocular lens that corrects common vision problems, including astigmatism. Patients with blurry vision can contact Dr. Besser’s practice in the heart of Culver City, California or use online booking to schedule a comprehensive eye examination and manage their cataracts.

Cataract Surgery Q & A

What causes cataracts?

The eye’s crystalline lens focuses incoming light onto the retina. A cataract develops when the lens loses its transparency, as proteins in the lens undergo structural and pigmentation changes. The resulting cloudiness gradually progresses over time, causing blindness if the cataract goes untreated.


What are the different types of cataracts?

One type of cataract occurs in young patients and progresses more rapidly than other types, but most cataracts correlate with aging, including:

Nuclear sclerosis

The most common age-related cataract, nuclear sclerosis, occurs when the center of the lens gradually hardens and yellows. The primary symptom of nuclear sclerosis is blurry vision. It also leads to poor night vision, nearsightedness, and makes colors appear less vibrant.

Cortical cataracts

Cortical cataracts affect the outer rim of the lens, which becomes white or cloudy. Excessive glare, especially at night, is the predominant symptom. It may affect near and distance vision.


How are cataracts treated?

Cataract treatment consists of surgical removal of the cloudy lens and implantation of a clear intraocular lens. Dr. Besser specializes in femtosecond laser-assisted cataract surgery using two state-of-the-art laser systems: the LenSx® Laser and Catalys®.

Both laser systems integrate the ultrashort-pulse femtosecond laser with 3D optical coherence tomography. With expert surgical skill, Dr. Besser performs sutureless cataract microsurgery, using the laser to create such a small and precise incision that the wound seals without stitches.

Femtosecond laser

Femtosecond lasers allow the cornea, lens capsule, and crystalline lens to be cut at precise depths and in various patterns. It uses low energy to soften the cataract, allowing gentle cataract removal.

Optical coherence tomography (OCT)

An OCT scan maps the eye’s structures, allowing cataract removal customized to the size and shape of each patient’s eye.


How are replacement lenses used to correct vision?

Following cataract removal, Dr. Besser implants the best intraocular lens for each patient, including lenses that correct common refractive errors such as:

  • Myopia (nearsightedness): clear vision of close-up objects, blurry distance vision
  • Hyperopia (farsightedness): clear vision of distant objects, difficulty seeing nearby objects
  • Presbyopia: develops with age, ability to focus up close becomes difficult
  • Astigmatism: near and distant images appear blurry and distorted

Dr. Besser may implant two advanced intraocular lenses: toric and multifocal. Toric lenses correct astigmatism, using different powers in various lens meridians to correct for varying degrees of nearsightedness or farsightedness. Multifocal lenses also correct for near and distance vision using different points of focus.
