Cataracts are one of the most common causes of vision loss. It is due to the loss of transparency of the crystalline lens, the natural eye lens. The crystalline lens loses its transparency both naturally and as a result of aging, reducing visual acuity. Although most cases are age-related, there are other types, such as congenital cataracts (present from birth) or secondary to certain diseases (uveitis, diabetes), drugs or ocular trauma.
Fortunately, medical advances have made cataract treatment safer and more effective than ever. Among treatment options, different cataract surgeries stand out for their techniques and technologies.
Traditional phacoemulsification
Phacoemulsification is the most common cataract surgical method. It involves using an ultrasound probe to fragment and aspirate the cataract. Once the opacified lens has been removed, an intraocular implant is inserted to restore vision. This technique is widely used because of its speed, efficiency and relatively short recovery time.
Laser phacoemulsification
It is possible to perform phacoemulsification using a laser at certain stages of the procedure. This approach offers greater precision, reducing the risk of complications. The laser can be used to create precise incisions in the cornea, fragment the cataract with great precision and soften the posterior lens capsule to facilitate insertion of the intraocular lens.
Femtosecond laser-assisted surgery
This cutting-edge technique uses a femtosecond laser to perform all stages of cataract surgery. The laser creates precise incisions in the cornea, divides the cataract into pieces and prepares the posterior lens capsule. Next, a surgeon inserts an intraocular lens to meet the patient's specific visual needs. Femtosecond laser-assisted surgery offers an unrivalled level of precision.
Toric Lens Cataract Surgery
Cataract surgery with a toric intraocular lens can be an effective solution for patients with cataracts and high astigmatism. This technique involves the insertion of a toric implant that corrects both cataracts and astigmatism. The ophthalmologist can help the patient achieve clear vision at all distances by correctly aligning the implant.
Different cataract surgeries offer patients customized options to improve their vision and quality of life. Technological advances continue to open up new possibilities for effective cataract treatment. Consult your trusted optometrist to discuss your options for cataract surgery.
