When the eye's natural lens, the crystalline lens, which has refractive power and allows us to focus on objects and allow light to pass through, gradually loses transparency , cataracts develop. This occurs as a natural part of the aging process.
The most effective treatment for this vision problem is cataract surgery using phacoemulsification and intraocular lens implantation . At Clínica Nivaria, we utilize the latest technological advancements to guarantee the best possible results.
Cataract surgery
Phacoemulsification is the most advanced method for the definitive treatment of cataracts . It involves using ultrasound to dissolve and remove the damaged lens, replacing it with an artificial intraocular lens that is deployed inside the eye without needing to enlarge the initial opening. This lens performs the same function as the natural lens, lasts a lifetime, and does not lose transparency.
What are the symptoms of cataracts?
- Blurred vision : causes the person suffering from cataracts to not see correctly, affecting their daily life.
- Improved vision : the patient may notice that their near vision improves, which may mean that a cataract is forming.
- Glare : the patient with cataracts presents greater sensitivity to light.
There are different types of cataracts.
- Nuclear cataract: This is the most common type, it develops in the center of the lens and is usually associated with advanced age.
- Subcapsular Cataract : This is the most common type in people with diabetes or chronic conditions, and is characterized by developing in the back of the lens.
- Cortical Cataract : Also related to advanced age, it develops in the outermost and lateral layers of the lens.
What is cataract surgery like?
Currently, phacoemulsification is the most advanced method for the definitive treatment of cataracts . It involves using ultrasound to remove and dissolve the damaged lens , replacing it with an artificial intraocular lens that is deployed inside the eye without needing to enlarge the initial opening. This lens performs the same function as the natural lens, lasts a lifetime, and does not lose transparency.
When is cataract surgery recommended?
At Clínica Nivaria, we perform a series of tests to assess the condition of the cataract and determine the optimal time for surgery, as well as a complete examination of the eyeball, including a retinal examination. All of this provides us with essential information to perform the surgery in a personalized way.
Cataracts typically appear after age 60. However, they can occur a few years earlier. This underscores the importance of a comprehensive eye exam for each patient. Cataracts are more common in nearsighted individuals, especially those with high prescriptions . In these patients, cataracts can develop at a much younger age.
What happens after cataract surgery?
The patient will regain vision from the first moment after surgery ; however, the recovery of visual quality will improve as the days go by.
Can cataracts and presbyopia be treated in the same procedure?
Yes, because replacing the natural lens with an intraocular lens can correct other refractive errors such as myopia, astigmatism, etc. There are monofocal lenses (good distance vision), bifocal lenses (good distance and near vision), extended-range lenses (good distance and intermediate vision), and trifocal lenses (the most advanced lenses currently available, covering distance, intermediate, and near vision). Each of these lenses has its specific indications according to the patient's eye condition and activity level. For example, not all patients are candidates for trifocal lenses.
