Every normally developed human eye contains within it a crystalline lens. This lens is a clear organ made up of proteins and it's responsible for focusing images on the retina, much like the lens inside a camera that brings images to focus on film.
With time and under the influence of factors such as ultraviolet lights, smoking, poor nutrition, radiation and/or chemotherapy, but most commonly as part of the aging process, the lens becomes cloudy. This occurs due to denaturation of the proteins that make up the lens. This process of clouding of the lens is irreversible and is called cataract formation. As the cataract forms, the light is scattered by the increasingly dense and cloudy lens and results in poor vision.
Patients between the ages of 65 and 70 are at risk of developing cataracts, with up to 50 percent of them suffering from visually significant cataracts that interfere with activities of daily living. Individuals who are on chronic steroid administration, have undergone radiation or chemotherapy, and have had trauma are at risk of developing cataracts at an even earlier age.
Cataract symptoms include halos, glare, a decrease of visual acuity, loss of color perception and contrast sensitivity. Frequently, symptoms are manifested as difficulty seeing road signs, seeing halos and glare from oncoming traffic, trouble reading and photosensitivity.
Most people with cataracts do not realize that they are suffering from a distortion on their lens, as initially any changes in vision may be undetected. The first sign of cataract formation may be when night vision begins to diminish. Fortunately, there are many advanced treatments for modern cataract surgery, without stitches or incisions.
Depending on the degree of the cataracts, a procedure with a leading cataract surgeon may be the only treatment option. The process involves breaking down the cataracts and removing them. As the cataracts were on the lens of the eye, that tissue is also removed and will need to be replaced with synthetic lenses, a process called intraocular lens (IOL) replacements.
The procedure to remove cataracts is one of the most common surgeries performed in America, with about three million procedures every year. The surgery takes very little time to complete and is painless. While you will be awake during the procedure, your eye will be numbed with local anesthesia, and you may have another medication to help you relax.
A very small incision is made on your eye, typically with a specialized laser. Another tool is then used to break up the natural lens and then extract it with gentle suction. Through the same incision, a synthetic lens is placed. If both eyes need cataract surgery, each eye is treated in a separate surgical appointment.
Modern cataract care involves the removal of a cloudy crystalline lens (the cataract) and its replacement with a clear intra-ocular lens implant or IOL. The use of intra-ocular lens implants (IOLs) is now considered to be the standard of care. Situations when it is not medically advisable or physically impossible to implant a lens are very rare. Before the advent of modern lens implants, patients were left aphakic (without lenses) and had to resort to use of very thick 'Coke bottle' glasses or contact lenses.
Other than the convenience of not having to wear 'Coke bottle glasses,' there are a number of medical reasons why it is important to have a lens implant. Aphakic eyes (eyes without lenses), are at higher risk of developing glaucoma and retinal detachments. That is why every reasonable effort is always made to place a lens implant in the eye.
There are a number of lens implant options available to the physician and the patient. These lenses all have a basic function of focusing images on the retina. Some lens implants have extended functions, such as correcting corneal astigmatism (Toric lenses) or allowing the eye to focus at both near and far distances, without having to resort to using glasses or contacts (Presbyopia Correcting Lenses). These IOL's with extended functions are usually not covered by health insurance or Medicare. That is because these lenses, while providing patients with the convenience of spectacle freedom, are not considered to be 'medically necessary' by most health insurers. The 'spectacle freedom' afforded by such extended function lenses comes with an added cost that is assumed by the patient.
Cost issues aside, not all lenses are appropriate for all patients. There are various factors that are individual to each patient that must be considered. If the idea of being glasses-free is enticing, about the premium cataract surgery options available at the Benjamin Eye Institute.
Once you decide you're ready to treat your cataracts and improve your vision, you will need to schedule a consultation with the team at Benjamin Eye Institute. During that appointment, you will undergo in-office preoperative testing and measurements. In addition to a full ophthalmic examination, one of the best cataract surgeons in Beverly Hills, Dr. Benjamin, will review the risks and benefits of cataract surgery with you, along with all of the treatment options that are available to meet your visual needs. Once your surgery is scheduled at our Los Angeles outpatient facility, we will review all of the details and schedule your final examinations. For more information about how to prepare for your surgery and what to avoid post-surgery, visit our page.
Typically, another visit is set to have biometrics performed:
These biometrics will assist in choosing the proper intraocular lens calculations. Logistical aspects of the surgery as well as medications are also discussed at this time.
Counseling will also take place during your appointments at our optometry office. This will include a discussion about the expectations concerning best corrected visual acuity (BCVA), including pre-operative conditions that may prevent perfect results, such as age-related macular degeneration. Counseling regarding uncorrected visual acuity (UCVA) may address goals of surgery, for example being left moderately nearsighted to allow near work to be performed without correction.
Patients with high amounts of astigmatism may not be able to rid themselves entirely of glasses. In this case, the doctor will talk to you about possible treatment modalities for astigmatism, including LRI and/or Toric IOL's. Possible upgrade to a multifocal/accommodating lens implants may be considered if the patient desires.
The eye structure includes what is termed a 'lens capsule,' which holds the lens. After cataract surgery, some patients experience what is often called a 'secondary cataract.' This is a condition in which the lens capsule (not the lens) becomes clouded. Other names for this condition are the medical term, 'posterior capsular opacification,' or an 'after cataract.' This condition can be treated with a laser procedure to restore clarity to that portion of the eye. It requires only a few minutes to complete this one-time corrective procedure.
If you have developed cataracts, it will impact your vision. The clouding of the lens associated with the clumping of proteins on the lens causes foggy, blurred, or clouded vision – all of which pose a danger when driving, and impact quality of life. Cataracts that are left untreated can lead to blindness – the most serious of all eye conditions. As the lens becomes thicker and harder it can cause inflammation or increased pressure within the eye, leading to glaucoma.
If cataracts are left untreated, the lens continues to thicken and harden, and can lead to blindness. Cataract surgery in which the lens is replaced with a synthetic lens can be performed on an eye in this condition, often restoring vision in that eye. It is advised that the surgery is performed before the patient has reached the point of low vision, as the thicker lens is more difficult to remove than one in a less severe condition. Worldwide, about 33 percent of the cases of blindness are the result of untreated cataracts, and 18 percent of cases of moderate to severe vision impairments.
While cataract surgery is a commonly-performed procedure – you want to ensure that you are under highly-professional care for this delicate surgery. At Benjamin Eye Institute in Beverly Hills, we are proud to be the premier eye care center serving the Los Angeles area.

When cataracts are causing blurry vision, it affects every aspect of your life. Clear, sharp vision can be restored with a carefully-performed cataract surgery. At our eye clinic in West Hollywood, we offer patients the option of placing high-tech, advanced interocular lenses that make wearing glasses or contacts unnecessary.
You may put your vision in the best hands by asking the proper questions of a potential LASIK physician using this No-Regrets Guide. We've included our own responses to these inquiries to prevent you from having to conduct an interview. But if you need more explanation or have other worries, let us know! We are at your service.
If you first experience a disaster like dry eye, the fundamental rule and recommendation would be to speak with a skilled ophthalmologist before putting anything in your eyes. Since choosing a treatment requires more pathophysiological understanding than simply purchasing the first eye drops you see.
Pterygium removal is a surgical procedure that removes abnormal tissue growing onto the cornea, often followed by a conjunctival autograft or amniotic membrane graft to support healing and reduce recurrence. This recovery guide explains what to expect after surgery, how to use prescribed ointments and drops, why UV protection is essential, how dry eye management supports healing, and when to contact our office during recovery.
Prokera® Slim is an FDA-cleared biological medical device that uses amniotic membrane to support healing of the ocular surface. This treatment may help reduce inflammation, suppress scarring, and restore damaged eye tissue in conditions such as keratitis, chemical burns, corneal scars, epithelial defects, and severe dry eye. Prokera is placed in the office, worn continuously for several days, and removed by Dr. Benjamin at a follow-up visit.
Valeda Light Delivery System is an advanced treatment for dry age-related macular degeneration, designed to support retinal cells and help preserve visual function. The procedure uses photobiomodulation — low-level light therapy with specific wavelengths — and is performed quickly, without pain, eye drops, injections, or recovery time.
If your vision becomes blurry, hazy, or foggy months or years after cataract surgery, it may be caused by posterior capsule opacification — often called a “secondary cataract.” This is a common and treatable condition, not a return of the original cataract. At Benjamin Eye Institute, Dr. Arthur Benjamin performs YAG laser capsulotomy in the office to quickly and painlessly clear the cloudy capsule behind the lens implant, with no incisions or stitches and clearer vision often restored the same day.
Blepharoplasty is a surgical procedure that rejuvenates the upper and/or lower eyelids by removing excess skin, fat, and muscle. This recovery guide explains what to expect after eyelid surgery, including swelling, bruising, cold compresses, suture removal, activity restrictions, and important instructions to support safe healing and the best possible aesthetic result.
Selective Laser Trabeculoplasty (SLT) is an in-office laser treatment designed to lower intraocular pressure in patients with glaucoma or ocular hypertension. This guide explains how SLT works, what to expect during the procedure, how Dr. Benjamin’s 180° treatment strategy is used, and why SLT may reduce or delay the need for daily glaucoma eye drops.
