Premium Iols

Premium IOLs for Refractive Lens Exchange

For patients who don’t qualify for laser eye surgery, intraocular surgery can be a very safe and effective alternative for vision correction. Intraocular surgery corrects vision by inserting a lens implant into the eye, almost like permanent contact lenses. Intraocular surgery can either be phakic, meaning the lens implant is inserted over the natural lens, or it can be a refractive lens exchange, in which a lens implant replaces the natural lens.

The lens implants are commonly referred to as IOL, or intraocular lens. While standard IOLs have been the most commonly used for decades, there are some setbacks. For one thing, standard IOLs are monofocal, so they can only correct vision at either near, intermediate, or far distances. You will need to depend on prescription lenses for whatever is not corrected. However, leading eye care centres like Clarity Laser Vision provide a number premium IOLS that offer more advanced features than standard IOLs.

Your Choice of Premium IOLs

The most common premium IOLs used at Clarity Laser Vision are:

  • AcrySof® IQ Toric IOLs by Alcon
  • AcrySof® IQ ReSTOR® Multifocal IOLs by Alcon

Types of Premium IOLS

Along with other features, premium IOLS provide a wide range of clear vision from near to far distances, thus further reducing the need for eyeglasses or contacts.You need to pick the premium IOLs that’s right for your eyes and your prescription, so remember to consult with an ophthalmic surgeon with extensive experience with premium IOLs like Dr. Al-Ghoul.

Accommodative: These lenses have the ability to move the eye to focus on near, intermediate, and far objects, much like how a real lens focuses.

Toric: These are similar to standard IOLs, but they have the added benefit of treating astigmatism, which is not usually directly treated by a lens exchange.

Extended Range: These IOLS have an intermediate to distant range, which are perfect for everyday use like driving or using a computer.

Multifocal: These lenses have multiple concentric circles with different focusing distances, thus allowing the patient to see in near, intermediate, and far distances.

Common Misconceptions about LASIK

LASIK has become one of the most common eye procedures today. More and more people are learning about the benefits of LASIK and going through with the procedure. What is more, the cost of LASIK has also dropped significantly over time. So why are so many people still avoiding the procedure? Unfortunately, there are still a lot of myths floating around about LASIK that hold people back. We are going to consider just a few of them:

I’m too old for LASIK.

Against what many people believe, there are many cases of successful LASIK procedures being performed on people even in their 50’s and 60’s! There is no upper age restriction when it comes to the LASIK procedure. That being said, there are some age-related eye conditions that could cause you to lose your candidacy for LASIK such as glaucoma and cataracts.

LASIK is too young of a procedure, and we don’t know the long-term side effects.

LASIK has been performed for over 25 years successfully, and long-term studies have already shown positive results. As technology has become more advanced, so has the procedure. There are very few possible complications.

LASIK is painful.

The fact of the matter is that LASIK is a very fast procedure lasting only about 15 minutes per eye and is generally pain-free. Numbing eye drops are applied right before the procedure to limit any discomfort, and while the patient may feel a small amount of pressure, most are surprised by how fast, easy, and painless it really is.

LASIK can cause you to go permanently blind.

There has not been one single recorded case of anyone going permanently blind from LASIK surgery. Complications related to LASIK are very rare, diminish over time, and are generally correctable.

Hopefully, these facts have made you more comfortable with LASIK so that you can get the vision that you deserve!

7 Causes of Low Vision: Are You at Risk?

Of all five senses, vision is most important for helping humans perceive and interpret our surroundings. Other animals are more reliant on their sense of smell. For us, eyes are the main sense organ, and much of our brain activity is a dedicated to visual input.

When eyesight is compromised, the result can be devasting. Severe vision loss that cannot be repaired with corrective lenses, medication or surgery, is called low vision. This extreme health condition is defined by the WHO as under 20/70 vision in the strongest eye, even with the best sight correction possible.

Common Causes of Low Vision

  • Age-related Macular Degeneration (AMD): The macula is the central part of the retina, which deteriorates with age. Since the retina is responsible for sharp focus on close objects, it determines what we see clearly in our center of vision. AMD impacts driving ability, facial recognition, reading, and work with fine detail. Macular degeneration is the leading cause of blindness in patients over 50 in the United States. It is also responsible for about 50 percent of low vision cases.
  • Glaucoma: This group of eye disorders eventually affects the optic nerve. The build-up of fluid cause pressure in the eye leading to damage and vision loss. Glaucoma develops due to drainage issues, too much fluid or problems with the release of fluid. This eye health condition is the second leading cause of blindness. Early detection is key to slowing down the progression of glaucoma and minimizing vision loss.
  • Retinitis Pigmentosa (RP): This grouping of eye diseases will destroy both peripheral and night vision over time. RP will progressively damage the light-sensitive rods and cones in the back of the eye. This is an inherited disease that is first presented as night blindness in adolescent or early adult years. Unfortunately, patients diagnosed with RP typically reach total blindness by age 40.
  • Diabetic Retinopathy: About 45 percent of diabetic patients are diagnosed with retinopathy. This eye condition causes retina damage gradually, and if left untreated, total blindness. Blood sugar fluctuations can damage blood vessels in the eye, causing the retina to swell. The result is cloudy or blurry vision. The best defense is to regulate blood sugar levels.
  • Amblyopia: The common term is a lazy eye, it affects the developing of one eye early in life. There is no eye health issue to blame; one eye just fails to develop properly in childhood. The key to reversing lazy eye is early diagnosis and treatment. Therefore, infants should have their first comprehensive eye exam by six months old, and another at age three. Without early treatment, the condition cannot be reversed.
  • Traumatic Brain Injury: Stroke, head trauma, and brain injuries can all cause a shift in the visual field, blurry vision, problems with depth perception, reduced visual acuity, eye misalignment, and glare sensitivity.
  • Cataracts: When the eye lens develops a cloudy film, light cannot get back to the retina. This causes vision loss. Cataracts are caused by genetic, injury, disease, sun exposure, injury and advanced age. The opaque layer can be surgically removed and replaced with a prosthetic lens to restore clear vision.

Many of these eye conditions and diseases can be treated and controlled if caught early. The most important step is to keep up with annual eye exams to help safeguard your eye health and help prevent low vision.

7 Reasons Why You Need an Eye Exam

  • You’ve been blowing it off for months…years…okay, centuries! The longer you wait, the worse many conditions can get. The worst thing you can do is wait until you have issues and then visit the doctor since there are many preventive treatments to help.
  • You have been wearing the same contacts for years. And that’s not a good thing; you get a new phone every year, so what about your contacts? There’s, new amazing tech in contact lenses now! Something that may not have been possible when you first got contacts could be a reality now.
  • You got used to looking through those scratches on your lenses. There is no need to suffer through an inferior or damaged product. Your eye health is way too important.
  • You sleep in your eye makeup. Bacteria and germs can easily get in the eye and cause infections. Anytime there is debris or leftover makeup near the eye, you run the risk. Listen, we know it happens, but get your eyes examined here and there to make sure all is good.
  • You are at risk of developing glaucoma. Knowledge is power and understanding how glaucoma can develop can help you prevent it. Ignoring an issue does not mean it will not happen to you, it just means that it can hurt you even more!
  • It’s NOT your boss, its computer eye strain! People have no idea how much damage work stress can do to your eyes. Let us help you with blue light and glare reducing technology.
  • Your eyes are red, itchy or dry. Your eyes love you, so love them back. Keep them healthy!

Talk to the Experts: Dr. Al-Ghoul Discusses Corrective Eye Surgery

Dr. Ahmed Al-Ghoul of Clarity Laser Vision recently sat down to talk with Whitney Dean at Talk to the Experts about corrective eye surgery, who may be a candidate and the different options a patient has to correct their eye condition permanently.

Are You a Candidate for Corrective Eye Surgery in SW Calgary?

When it comes to corrective eye surgery, it is extremely important to determine whether or not the patient is a candidate for the specific procedure. Age can be a major factor as the eyes need to be stable in order for corrective eye surgery to be successful. Patients must also be in good optical health and overall health as certain conditions may make treatment less successful.


The LASIK procedure is performed using ultraviolet lasers. First, a thin flap is creating in the patient’s cornea, the flap is then pulled back, and an excimer laser microscopically sculpts the cornea. Once sculpted, the flap is placed back to heal properly.

Touchless Surface Ablation (TSA)

The TSA procedure is performed using a unique laser algorithm and removed the epithelium (outermost layer of a patient’s cornea) prior to reshaping the cornea using an excimer laser. TSA is a completely touchless corrective eye surgery option.

Refractive Lens Exchange

Unlike other corrective eye surgery procedures, a refractive lens exchange does not change the structure of your cornea. Instead, we exchange the lens itself with an artificial implant called an intraocular lens (IOLs).

Common Eye Care Medical Terms

During your regular appointments with your optometrist at Clarity Laser Vision, you may hear a variety of eye care medical terms you are not familiar with. We want to provide you with definitions of common terms you may hear during your next appointment to better understand what your eye doctor is telling you. Read on to learn 10 eye care medical terms.

  • Age-related macular degeneration. This is an eye disorder that can damage the retina and affect vision loss in certain areas.
  • Amblyopia. This is when one eye lacked in development and cannot be corrected with glasses. It is commonly known as a “lazy eye” and can be fixed with a patch or vision therapy to strengthen the eye.
  • Astigmatism. This is an irregularly shaped cornea or lens that causes blurry vision from the light not properly focusing.
  • Cataract. Cataract causes loss of vision from a cloudy part of your lens.
  • Glaucoma. This is several eye disorders that can cause nerve damage and damage to tissues. Glaucoma can lead to blindness.
  • Hyperopia. Hyperopia is also known as farsightedness. This makes it hard for an individual to focus on close-up objects.
  • Myopia. This is also known as nearsightedness. This makes it hard for an individual to see far away objects.
  • Presbyopia. This is similar to hyperopia but is affected by the individual’s age.
  • Visual Acuity. This is the measurement of the sharpness of an individual’s vision at 20 feet.
  • Vision Therapy. This is a therapy for your eyes. Your eye doctor will provide you with different exercises to strengthen your eye muscles and focus.
