Surgeries that change lives
Cataract surgery is done today with the technique phacoemulsification. This uses a fluid system and ultrasound which serves to disappear the cataract.
2.2 mm incisions are made so no concerns for points or suture are present, and this facilitates visual recovery
You must place an intraocular lens for the final vision. There are a variety of intraocular lenses with different properties which your doctor will recommend the best choice for you.
A corneal transplant (also known as keratoplasty or corneal graft) involves removing the central portion of a diseased cornea and replacing it with a donor cornea.
The cornea is the clear part of the eye located in front of the iris and pupil.
This procedure is performed when the patient’s eyesight is affected due to scarring or damage caused by injury or disease.
The fundamental goal of glaucoma treatment is to reduce intraocular pressure; this can be achieved with the use of drops that decrease aqueous humor formation in the eye, or drops to facilitate aqueous humor outflow.
In patients where the drops are not sufficient to lower intraocular pressure the following surgical procedures are recommended:
- Placing Ahmed valve
- Laser iridotomy
Corneal ring surgery
They are polymethylmethacrylate ring segments which are inserted into the intermediate periphery of the corneal stroma.
The purpose of the corneal rings is to modify the corneal curvature, improving the distortion of images.
This procedure is to slow the progression of keratoconus.
It is a Collamer lens which is implanted into the eye of the lens and below the iris, so it is not seen with the naked eye.
This option is left for patients with high myopia of more than 8 diopters or people who have moderate or high myopia with thin corneas.
The ICL lens corrects nearsightedness and astigmatism and is well tolerated by the patient, improving contrast and final visual quality.
PRK surgery & Streamlight
Photorefractive keratomileusis is an option for patients with a thin cornea or ocular surface disorders.
Many of the patients who are recommended this procedure are people with demanding physical activities or people who like extreme sports. Since no flap tissue procedure is performed, this decreases the chance of a possible displacement in the future.
LASIK are the initials in English of laser in situ keratomileusis. This procedure involves creating a corneal flap cutting directly some stromal tissue with an excimer laser, which flattens the cornea to treat end myopia or increases its slope to correct farsightedness.
A good candidate must have at least 18 to 21 years of age and should have a stable refraction. Patients with ocular disorder, such as severe dry eye syndrome, uveitis, systemic diseases or those taking drugs that alter wound healing, are poor candidates.
Keratoconus, an abnormality in the cornea conical and irregular, is a contraindication for surgery because the results are unpredictable. It should be an analysis of the corneal curvature, often through a corneal computerized topography for all preoperative patients, because early keratoconus has a prevalence up to 25% in this population and may go unnoticed with other diagnostic means.
