Does your vision feel as if you were looking through a misted-up window? That is how many people experience everyday life with cataracts, one of the most common causes of vision loss worldwide, especially in older people. Although the word “cataract” may cause concern, the good news is that it is a treatable condition, with a highly safe and effective surgical procedure that can restore vision. At Clínica Ramírez & Gálvez, we offer you a complete guide to cataracts so that you can regain the clarity and quality of life you deserve.
What Are Cataracts? Understanding Clouding of the Lens 🤔
Inside your eye, behind the iris, there is a natural lens called the crystalline lens, which focuses light onto the retina so that you can see sharply. A cataract occurs when this lens becomes opaque or cloudy, preventing light from passing through properly. It is as if a camera lens had fogged up, causing blurred or reduced vision. Cataracts usually develop slowly, affecting vision progressively over time.
Causes of Cataracts: Beyond Age 🧐
The most common cause is ageing, as with age the proteins in the lens clump together, forming opacities. Other factors that can play a part include genetics, diseases such as diabetes (due to high glucose levels), eye injuries 💥, prolonged use of certain medicines (corticosteroids) 💊, exposure to UV radiation ☀️, and habits such as smoking.
Symptoms of Cataracts: When Should I Be Concerned? ⚠️
Cataracts progress painlessly and symptoms vary, but the most noticeable include:
- Blurred or cloudy vision: Like looking through a misted-up window.
- Difficulty seeing at night: A significant reduction in night vision and problems with glare. 🌙
- Sensitivity to light and glare: Intense discomfort with bright lights or headlights. ✨
- Halos around lights: Seeing rings of light.
- Faded or yellowish colour perception: Colours look less vivid. 🎨
- Needing to change your glasses prescription frequently.
Diagnosing Cataracts: A Complete Eye Examination 🔍
Cataracts are diagnosed by an ophthalmologist through a complete examination. At Clínica Ramírez & Gálvez, we use advanced technology for an accurate diagnosis:
- Tonometry: Measurement of intraocular pressure.
- Slit-Lamp Examination: Detailed inspection of the lens.
- Pupil Dilation: For a better view of the lens and the back of the eye.
- Ocular Biometry: Precise measurement of the eye to calculate the power of the intraocular lens. 📐
- Optical Coherence Tomography (OCT) / Corneal Topography: To assess the retina and cornea.
Modern Cataract Surgery: Restoring Clarity 🔪
Surgery is the only effective treatment for cataracts. It is one of the most common and safest surgical procedures, with high success rates, and is usually performed as a day case.
The most common procedure is phacoemulsification:
- Anaesthesia: Topical or local, for a painless procedure.
- Minimal Incision: A small incision at the edge of the cornea.
- Fragmentation and Aspiration: The cloudy lens is broken up with ultrasound and aspirated.
- Intraocular Lens (IOL) Implant: A clear artificial lens is placed to replace the natural lens.
Types of Intraocular Lenses (IOLs): Personalising Your Vision 🤓
Advances in IOLs make it possible to personalise vision after surgery:
- Monofocal Lenses: Clear vision at a single distance (usually far), requiring glasses for near vision.
- Multifocal / Trifocal Lenses: Allow you to see at distance, near and intermediate ranges, reducing the need for glasses for most activities.
- Extended Depth of Focus Lenses (EDOF / Monofocal Plus): Good distance and intermediate vision, with glasses possibly needed for fine reading.
- Toric Lenses: Correct astigmatism at the same time as the cataract.
The choice is made in consultation with your ophthalmologist, according to your lifestyle and needs.
Recovery after Cataract Surgery: 🧘♀️
Recovery is usually quick and involves little discomfort. Some irritation or blurred vision at first is normal. Eye drops are used to prevent infection. Most people return to their activities within a few days, although vision stabilises over a few weeks.
