For light to pass smoothly through the eye, the lens must be transparent to avoid any refraction or reflection that obstructs light from reaching the retina (الشبكية). In its natural state, the eye's lens is clear and efficiently facilitates light passage. However, changes can occur in the lens, leading to opacities that hinder light transmission. This condition is known as cataracts.
Cataracts are among the most common eye health issues affecting vision and causing significant discomfort. This article will delve into cataracts, exploring their causes, symptoms, and complications. We will also discuss cataract surgery costs and answer key questions like: Can cataracts be treated without surgery? And do cataracts cause blindness? This information is provided by specialized ophthalmologists, including Dr. Mahmoud Hassan - Vitreoretinal Surgeon at Mashreq Eye Center, Cataract and Refractive (تصحيح الإبصار) Surgery Specialist, Fellow of the International Council of Ophthalmology (طب وجراحة العيون), and Member of the Royal College of Surgeons England. Read on for comprehensive details.

Causes of Cataracts
Let's begin by understanding the causes of cataracts. Naturally, the lens is flexible and transparent, allowing light to pass through easily. However, with age, typically around 40, the proteins in the lens start to break down and clump together, forming a cloudy spot. Light cannot pass through this opaque area, affecting vision quality. Over time, this cloudy part expands, potentially covering the entire lens. This leads many to ask, "Do cataracts cause blindness?"
In addition to aging, several risk factors can increase the likelihood of developing cataracts:
Underlying health conditions like diabetes.
Excessive alcohol consumption.
Family history of cataracts.
Direct eye injuries, previous eye surgery, or radiation therapy to the upper body.
Excessive exposure to sunlight.
Long-term use of steroid medications (corticosteroids), whether as pills, inhalers, or eye drops.
These factors significantly increase the risk of cataracts. However, their presence doesn't guarantee cataract development but highlights the importance of proactive eye care and consulting a doctor for preventive measures.
Symptoms of Cataracts
Following our discussion on causes, let's explore the symptoms of cataracts and how they impact a patient's quality of life. Cataracts lead to numerous symptoms affecting vision clarity:
Frequent need to change eyeglass or contact lens prescriptions.
Cloudy or blurry vision.
Colors appearing faded.
Difficulty seeing clearly at night.
Lights appearing too bright.
Seeing halos around lights.
Double vision.
It's important to note that early-stage cataracts may not present noticeable symptoms, especially when the opaque area is small and minimally affects light transmission. As the condition progresses and the opaque region enlarges, symptoms become more pronounced and bothersome. Therefore, seeking professional medical advice upon experiencing any of these symptoms is crucial for timely assessment and treatment.
Complications of Cataracts
Cataracts, the clouding of the eye's natural lens, can lead to several complications if left untreated. Here are some potential issues:
Difficulty with reading and daily activities.
Light sensitivity and glare.
Double vision in one eye.
Changes in color perception.
Loss of night vision.
Increased risk of falls and injuries.
Do Cataracts Cause Blindness?
One of the most frequently asked questions after a cataract diagnosis is, "Do cataracts cause blindness?" This stems from the significant concern this condition raises, given the vital role of vision in human life and the profound impact of its loss.
Before answering, let's clarify that blindness isn't a single entity. There are two types: functional blindness, where the vision loss is temporary and reversible once the underlying cause is treated, and permanent blindness, which is irreversible, often due to irreversible optic nerve damage.
To answer whether cataracts cause blindness: yes, but of the functional type. Cataracts obstruct light passage to the retina and scatter light rays. However, once the cataract is treated, vision is typically restored.
Non-Surgical Treatment for Cataracts
Many people inquire about non-surgical cataract treatment due to apprehension about surgery. It's important to understand that non-surgical approaches do not offer a definitive cure for cataracts; they are merely attempts to manage the condition and alleviate symptoms. The only effective and permanent treatment for cataracts is surgery.
In the early stages of cataracts, non-surgical management may involve the following recommendations:
Using brighter lighting at home and work.
Wearing anti-glare sunglasses.
Using magnifying lenses for reading or other activities.
Avoiding driving at night.
These non-surgical methods aim to mitigate issues. Additionally, appropriately prescribed eyeglasses or contact lenses can help improve vision in mild cases of cataracts.
Cataract Treatment
When a patient's condition significantly worsens, severely impacting their ability to perform daily activities, surgical intervention becomes necessary. Surgery is the effective and definitive solution for cataracts. During the procedure, the clouded natural lens is replaced with a clear artificial intraocular lens (العدسة داخل العين) (IOL (العدسة داخل العين)), restoring the patient's vision.
Cataract surgery is generally a very safe procedure with a high success rate. It's crucial to choose experienced surgeons like Dr. Mahmoud Hassan - Vitreoretinal Surgeon at Mashreq Eye Center, Cataract and Refractive Surgery Specialist, Fellow of the International Council of Ophthalmology, and Member of the Royal College of Surgeons England - for precise execution and to minimize potential complications. Utilizing the latest surgical techniques and IOLs is also paramount.
Cost of Cataract Surgery
Cataract surgery can be performed using various methods, including femtosecond (فيمتو ثانية) laser or traditional surgical techniques, making it difficult to provide a fixed cost. Several factors influence the overall expense. Generally, laser-assisted cataract surgery might start from approximately 20,000 EGP.
Factors affecting the cost include:
Anesthesia and surgical instrument fees.
Pre-operative examination costs.
Type of intraocular lens used.
Surgical technique employed.
Expertise and experience of the surgeon and medical team.
Level of services provided by the hospital or medical center.
It is advisable to discuss the cost of cataract surgery with your surgeon before the procedure. You can contact Dr. Mahmoud Hassan's clinic for detailed information.
In conclusion, cataracts are a prevalent eye condition significantly impacting vision quality. Choosing the best surgeons for precise cataract surgery is essential for restoring sight.

What is the cause of cataracts?
Cataracts are caused by the breakdown and clumping of proteins in the eye's lens, forming an opaque area that light cannot pass through. Additional contributing factors include eye injuries and certain medical conditions like diabetes.
Can cataracts be removed without surgery?
Unfortunately, cataracts cannot be removed without surgical intervention, which involves replacing the clouded natural lens with an artificial one.
