Cataract Symptoms and Laser Cataract Surgery

Cataract symptoms typically manifest as slowly developing blurred vision, fading of colors, and increased sensitivity to glare when driving at night. This condition, which occurs as the eye's natural lens loses its transparency over time, directly impacts your quality of life. In advanced cases, the only permanent solution is cataract surgery, which now offers a highly comfortable and rapid recovery process thanks to the advancement of laser technologies.

At a Glance

• A cataract is the clouding of the natural lens inside the eye as it loses its transparency.
• The most common complaint is the sensation of constantly looking through a dirty or foggy window.
• Although it is generally seen in individuals over the age of 60, it can also occur at earlier ages due to reasons like diabetes or trauma.
• It cannot be treated with glasses, medications, or eye drops; the only solution is surgical intervention.
• Thanks to modern laser surgery, the procedure time is shortened, and patients can quickly return to their daily lives.

What is a Cataract and Who Gets It?

Inside our eye, there is a natural lens that refracts incoming light onto the retina, allowing us to obtain a clear image. Highly flexible and completely transparent in our youth, this structure begins to cloud over as we age due to the breakdown of proteins within it. The loss of transparency and the lens becoming opaque is called a cataract. It is the most common cause of vision loss among the elderly in Türkiye and around the world.

It mostly presents as a slowly developing process in individuals aged 60 and over. However, it would be incomplete to think of it merely as a disease of old age. It can also be seen in infants due to congenital reasons, in young people following a severe blow to the eye, or in middle-aged individuals as a result of systemic diseases. This decline in visual quality makes daily activities increasingly difficult, whether it's reading the signs on a passing dolmuş (local shared taxi), driving, or recognizing faces in a bustling Istanbul crowd.

Causes and Risk Factors

The most fundamental factor in the development of cataracts is the aging process. As the years pass, the regeneration rate of the cells in the eye lens decreases, and protein build-ups disrupt the lens's transparency. Alongside aging, genetic predisposition plays a significant role; individuals with a family history of cataracts are more likely to experience this condition.

Environmental factors and lifestyle choices also accelerate the process. Prolonged, unprotected exposure to the sun's harmful ultraviolet (UV) rays, especially during the summer months, causes damage to the lens structure. Smoking and heavy alcohol consumption directly threaten eye health by increasing oxidative stress in the body.

Chronic diseases are also high on the list of risk factors. Uncontrolled diabetes can disrupt the fluid balance inside the eye, bringing cataract formation forward by years. Additionally, long-term cortisone use, blunt or penetrating trauma to the eye, previous intraocular surgeries, and high myopia are conditions that pave the way for early clouding of the lens.

What Are the Symptoms of Cataracts?

In the early stages of the disease, you may not feel any symptoms because the clouding covers a very small area of the lens. However, as this area expands over time, the most prominent complaint—blurred vision—emerges. Patients often describe this situation as constantly looking through dirty glasses or walking in foggy weather. Although symptoms vary depending on age and the type of cataract, they severely complicate daily life as the process advances.

Common symptoms include:

• Being excessively dazzled by the headlights of oncoming traffic while driving at night and seeing halos around lights.
• Colors not being perceived as vibrantly as before, with whites in particular appearing yellowish or faded.
• Needing much brighter light than before when reading, sewing, or doing detailed work.
• Frequent changes in glasses or contact lens prescriptions, with current glasses becoming inadequate.
• The onset of double vision or seeing objects with a shadow.

Because these symptoms develop gradually, patients often try to adapt to the situation, but the decline in visual quality is permanent and requires intervention.

Diagnosis: How is it Diagnosed at the Hospital?

When you consult an ophthalmologist regarding changes in your visual quality, the diagnostic process begins with a highly painless and detailed examination. Your doctor will first perform a visual acuity test to measure how clearly you can see letters or symbols from a certain distance. Then, the front structures of the eye—the cornea, iris, and lens—are examined in detail using a special device called a biomicroscope (slit lamp). This examination accurately determines the location and density of the clouding in the lens.

Your pupils are dilated with special drops to examine the retina and optic nerve at the back of the eye. This step is critical to understand if there is another underlying disease causing the vision loss. Sometimes, patients may also present to the doctor with headaches accompanying blurred vision. As we mentioned in our article titled Not every headache is stress: Your eyes might be giving a signal!, refractive errors or strain caused by cataracts can trigger headaches. An accurate diagnosis forms the foundation of proper surgical planning.

Treatment: Laser Cataract Surgery and the Recovery Process

It is not possible to treat cataracts with medication, eye drops, diet, or any home care method. Since there is no medical compound that can restore the clouded lens structure to its transparent state, the only valid treatment method is cataract surgery, where the clouded lens is removed and replaced with an artificial intraocular lens (IOL). Offering much more precise results compared to traditional surgery, laser cataract (femtosecond laser) technology performs the most critical stages of the operation using computer-controlled laser beams.

During the procedure, the eye is numbed with drops, so the patient does not feel any pain or aching. With the help of the laser, a perfect window is opened in the front membrane of the eye, and the hardened cataract is divided into small pieces using laser waves. Then, using ultrasonic sound waves (phacoemulsification method), these pieces are vacuumed away. A clear, permanent artificial lens suitable for the patient's eye structure is placed into the empty capsule. This entire procedure generally takes 15-20 minutes.

Patients are discharged on the same day. Mild stinging or watering is normal for the first few days of the recovery process. Regular use of the antibiotic and cortisone eye drops prescribed by the doctor prevents the risk of infection and accelerates healing. Achieving full visual acuity usually takes a few weeks.

Complications and Risk Groups

When left untreated, a cataract not only reduces visual quality but can also lead to other problems that seriously threaten eye health. Over time, the clouded lens can swell and obstruct the circulation of intraocular fluid. This can cause a sudden spike in eye pressure (glaucoma), leading to permanent damage to the optic nerve. Furthermore, in advanced cases where the cataract has become very hard, surgical intervention becomes technically more difficult, and the postoperative recovery period lengthens.

Postoperative complications are quite rare in modern surgery. However, risks such as infection, intraocular bleeding, retinal detachment, or fluctuations in eye pressure are present, as with any surgical procedure. Diabetic patients, those with severe myopia, and individuals who have previously suffered eye trauma are in a higher risk group for complications. Sometimes, months or years after the surgery, the membrane behind the artificial lens can become cloudy (secondary cataract). This condition is permanently resolved with a simple, few-minute YAG laser procedure performed in an outpatient clinic setting.

When to See a Doctor?

Any change in your sense of sight should be taken seriously, and you should consult a specialist without delay. Although a cataract is usually a slowly progressing condition, some symptoms can be harbingers of different eye diseases that require emergency medical intervention. When you start having difficulty performing your daily tasks, feel that your glasses prescription is no longer sufficient, or experience severe glare during night drives, you should schedule a routine eye examination.

If you experience any of the following emergency warning signs, you should immediately go to the nearest hospital's emergency department or call 112:

• Sudden, complete loss of vision in one or both eyes, occurring within seconds or minutes.
• Severe, unbearable pain and a throbbing sensation in or around the eye.
• A black curtain or dark shadow descending to cover a portion of your field of vision.
• A sudden onset of dense, floating black spots accompanied by flashes of light.
• Severe nausea and vomiting developing alongside sudden redness in the eye.

Frequently Asked Questions

How long does cataract surgery take?

The surgical procedure is generally completed in 15 to 20 minutes for a single eye. Including the patient being taken to the operating room, the preparation process, and resting afterward, the average hospital stay is a few hours.

Is laser cataract surgery painful?

Before the procedure, the surface of the eye is completely numbed with special drops. Thanks to this, patients do not feel any pain, aching, or soreness during the surgery; only a slight sensation of touch or pressure may be perceived.

Can a cataract recur after surgery?

Because the clouded natural lens is completely removed and replaced with an artificial lens during cataract surgery, it is impossible for the cataract to recur. Sometimes, the membrane where the lens is placed may become cloudy years later, which is corrected in seconds with a simple laser procedure.

Can a cataract occur in just one eye?

Yes, a cataract can start and progress in only one eye. However, it is generally a condition that affects both eyes; the clouding in one eye may simply develop faster and show symptoms earlier than the other.

Can cataracts be cured with medication or drops?

No, it is scientifically impossible to reverse or treat cataracts with medication, eye drops, eye exercises, or dietary changes. The only treatment for a deteriorated lens structure is replacing it through surgical methods.
