How an Eye Exam is Performed

Optometrists and ophthalmologists use a wide variety of techniques to examine your eyes during a comprehensive eye exam. These tests range from the simple, like having you read an eye chart, to the complex, such as using a high-powered lens to visualize the tiny structures inside of your eyes. A comprehensive eye exam can take an hour or more, depending on your doctor and the number and complexity of tests required to fully evaluate you. It is through these tests that you can determine if you may a candidate for a procedure such as LASIK or cataract surgery. For more information on cataract and LASIK surgery in Orange County, contact the experts at Advanced Eye Medical to schedule your eye exam.

Here is what you can expect during a comprehensive eye exam:

Color Blindness Test

A color vision screening is often performed early in the eye exam process. In addition to detecting color blindness, this can also alert your doctor to eye health defects that affect your color vision.

Cover Test

During this test, your doctor will cover each of your eyes individually and ask you to look across the room at a far object, then closer at a near object. By having you fixate on these two separate targets with each eye, your doctor can see weather the eye has to move in order to “pick up” the target. If it does have to move, this could indicate strabismus or a subtler binocular vision problem that could cause eye strain or “lazy eye.”

Ocular Motility (Eye Movement) Testing

These tests show how well your eyes can follow a moving target or move rapidly between two targets. The more common test is of smooth eye movement, or “pursuits.” Your doctor will have you hold your head still and follow a small light or other object from side to side using only your eyes. Less frequently, doctors may test quick eye movements, or “saccades,” by having you move your eyes back and forth between two objects placed with some space in between. Potential problems with eye movements are problems with eye strain, reading ability, and sports vision.

Stereopsis (Depth Perception) Test

The term “stereopsis” describes the way your two eyes team up to create depth perception as well as a 3-D view of the world. In one commonly used stereopsis test, you are asked to wear 3-D glasses while looking at a booklet of test patterns. The booklet will have images of shapes that appear closer and farther away, and you will be asked to identify which shape appears to be closest to you. If you can identify the correct shape, it means you have excellent eye-teaming ability.


This test is performed early in the exam to get an approximation of your eyeglass prescription. Your doctor will ask you to stare at the big “E” at the top of an eye chart. As you stare at the “E,” your eye doctor will shine a light at your eye and flip lenses in a machine in front of your eyes. This test estimates which lens powers will best correct your distance vision.


While looking at an eye chart on the wall, the doctor presents you with various lenses to look through and asks which offers you the clearest view of the letters on the chart. This is how the doctor determines your exact eyeglass prescription.

Slit Lamp Exam

A slit lamp is a binocular microscope (or “biomicroscope”) that your eye doctor uses to examine the structures of your eye under high magnification. During the slit lamp exam, you will be asked to place your forehead and chin on rests on the front of the instrument. Your doctor will begin by examining the structures of the front of your eyes, including your eyelids, cornea, conjunctiva, iris, and lens.

With the help of a hand-held lens, your doctor may also use the slit lamp to examine structures located farther back in the eye, such as the retina and optic nerve.

A wide range of eye conditions and diseases can be detected with the slit lamp exam, including cataracts, macular degeneration, corneal ulcers and diabetic retinopathy.

Glaucoma Test

This is the “puff of air” test, technically known as non-contact tonometry, or NCT. Based on your eye’s resistance to the puff of air, the machine calculates your intraocular pressure (IOP). If you have high eye pressure, you may be at risk for or have glaucoma.

Pupil Dilation

Your doctor may use dilating eye drops to obtain a better view of your eyes’ internal structures. This allows for the most thorough evaluation of eye health. Make sure to bring sunglasses for the ride home, because you will be more sensitive to sunlight when your pupils are dilated.

Visual Field Test

In some cases, your doctor might check for blind spots, or scotomas, in your peripheral vision. These can be caused by eye diseases such as glaucoma, or brain damage from stroke or brain tumors.

Can Cataracts Be Cured?

As unfortunate as it may sound, cataracts play a common role in the natural aging process. As our eyes grow older, the lenses in our eyes can suffer from time-telling wear and tear.

Cataracts are identified by the filmy, milky layer that forms on top of the eye’s lens. These cataracts can accumulate and grow over time, and their presence can seriously harm and reduce a person’s vision. If you are worried about the effects of cataracts, and if you or someone you know is suffering from cataract-like symptoms, we are here to provide help and reassurance that your eyes can be treated the right way.

Unfortunately, there is no way to prevent cataracts from forming. But there is still hope!

At Advanced Eye Medical, we value the health and longevity of your vision. Your eyes are some of the most important and sensitive parts of the body, and losing vision could result in the serious loss of daily functions and abilities. Don’t wait until it’s too late! View our numerous treatment options below for cataract surgery in Orange County to see how your cataracts can be reduced, removed, or cured altogether.

Symptoms of Cataracts

Before reviewing the list of possible treatment options with Advanced Eye Medical, you should fully understand what separates cataracts from other vision-impairing ailments. While cataracts are common in senior citizens, people of any age can contract them at any time. While there are a variety of reasons for this, the general consensus remains that there is no way to prevent their formation.

Here are some of the more common symptoms of cataracts on the lens:

● Increasingly blurry vision

● Increasingly poor vision

● The need for bright lights in order to read text

● Lights appear as if they have rings around them

● Double vision in one or both eyes

● Constant increase in prescription strength for your glasses or contacts

When cataracts begin to form on your eye, it may feel like you are starting to lose your vision. While the optic nerve itself is not losing the ability to see, your vision becomes impaired because the filmy substance is spreading over your eye. Think of it like putting a cap on the end of a camera lens – when you look through it, you can’t see a thing.

It’s important to note that cataracts do not cause pain or irritation. While they will impair your vision, and become irritating to deal with, they will not cause discomfort otherwise.

Cataracts Treatment Methods

Surgery is often the most recommended type of cataract removal treatment. While the conditions and specifications of the surgery can change from person to person, the overall treatment plan is the same.

During cataract surgery, our top surgeon, Dr. Ghosheh at Advanced Eye Medical, will use state-of-the-art removal equipment to safely, efficiently, and painlessly take away the cataracts from your lens.

Here’s how the process goes:

1. Dr. Ghosheh will make a small incision on the lens of the eye itself, which will cause no pain or vision interruptions.

2. A miniscule tool will be inserted into the incision, which will break up the cataracts material and remove the cloudy lens.

3. Dr. Ghosheh will then insert a state-of-the-art intraocular lens, also known as an IOL, into the tiny incision slit. This will permanently rest on top of your eye as a new lens, free from cataracts or other vision impairments.

Did you know that cataract removal surgery is completely pain free, and only takes about 20-30 minutes to complete? Not only is the surgery the most highly effective surgery in the vision industry, but it also promises that the patient’s eyes will return to normal by the very next day. This means you won’t have to wait around during recovery time. You can return to work, attend to your chores, and perform your daily activities in no time.

Types of Intraocular Lenses

Our talented professionals at Advanced Eye Medical are passionate about using the latest and greatest devices possible. The new generation of IOLs introduces four new types of IOLs that patients can pick from:

1. Monofocal Lens – This is great for long-distance vision issues.

2. Multifocal Lens – This is the perfect option to restore reading vision as well as far-reaching vision.

3. Astigmatism Lens – Do you struggle with astigmatism? These lenses can be inserted easily and painlessly to treat your astigmatism.

4. Accommodating Lens – This specially-designed lens is designed to combat vision loss, stimulating the muscles in your eyes and giving you much-deserved eyesight strength.
