When the natural lens of the eye, the crystalline lens, which has refractive capacity and allows focusing on objects and the passage of light, progressively loses transparency, cataracts occur. This occurs as a natural part of each person's aging process.
The most effective treatment alternative for this visual problem is the operation of cataracts through phacoemulsification and implantation of an intraocular lens. In Nivaria Clinic We have the latest technological advances to guarantee the best results.
What are the symptoms of cataracts?
- Blurred vision: makes the person suffering from cataracts not seeing correctly, affecting their daily lives.
- Improvement of vision: it may be the case that the patient perceives that their near vision improves, which may mean that the cataract is forming.
- Glare: the patient with cataracts has a greater sensitivity to light.
There are different types of cataracts.
- Nuclear Cataract: It is the most common, it develops in the center of the lens and is usually associated with advanced age.
- Subcapsular Cataract: It is the most common in diabetic people or with chronic treatments, 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.
How is cataract surgery?
Currently, phacoemulsification is the most advanced method for the definitive treatment of cataracts. It consists of the use of ultrasound to extract and dissolve the damaged lens, to replace it with an artificial intraocular lens that is deployed inside the eye without expanding the initial opening. This lens performs the same function as the lens, lasts a lifetime and does not lose transparency.
When is the cataract operation recommended?
What happens after the cataract operation?
The patient will recover 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 intervention?
Yes, since replacing the natural lens with an intraocular lens can correct other refractive problems such as myopia, astigmatism, etc. There are monofocal lenses (good distant vision), bifocals (good distant and near vision), extended range (good distance and intermediate vision) and trifocals (they are the most advanced lenses of the moment and covers distant, intermediate and near vision). Each of these lenses has its indication according to the ocular state and the activity of the patient. Take as an example that not all patients can be candidates for trifocal lenses.
Different refractive defects such as myopia, hypertherotopia and ASTIGMATISM, so far corrected only through the use of glasses or contact lenses, with the corresponding limitation in the quality of daily life, hobbies, work, etc. of its users, now have the development of the Excimer Laser technique that allows such correction, offering the
Intraocular lens surgery The phakic lens is an intraocular lens that is added to the eye's optical system without removing any structure. This lens allows the eye to properly focus light rays on the retina. These lenses can correct high diopters in myopia, farsightedness and astigmatism. Intraocular lens implants respecting the
Presbyopia Surgery Presbyopia, better known as "tired eyesight" refers to the progressive appearance of difficulty focusing near images (reading, mobile phone, computer monitor ...) when there was no such problem before. This phenomenon generally occurs after the fourth decade of life, due to the hardening of the lens and the weakening
