ABOUT CATARACTS

What is a cataract?
A cataract is the opacification of the natural lens of the eye due to age, or other causes such as ocular trauma or inflammation, among others.


What are its symptoms?
A cataract starts out small. It has little effect on vision at the beginning. You may notice that your vision is blurred, like looking through a cloudy piece of glass. Cataract can also produce glare with the sunlight, lamps or headlights at night.
As the cataract develops, your vision will be increasingly blurred, interfering in daily activities.


How is a cataract treated?
A surgical approach is the only way. The cataract is removed by the Phacoemulsification technique, and the clouded lens is replaced with an intraocular lens.


When should a cataract be treated?
Generally, I recommend surgery when the patient is not able to safely do his/her daily activities.


Is there any pain?
Phacoemulsification is nearly painless, during and after the procedure. We are using mixed anesthesia of drops and  periocular injections. Most patients only refer some discomfort during the surgery due to the instruments used to prevent the eye moving or blinking. The day of the operation you can feel some little itching.


What are the post-operative restrictions?
The day of the procedure, you are requested to rest as much as possible.
You will use antibiotic and anti-inflammatory eye drops for two weeks.
Rubbing your eyes is not allowed for a month .
You can practice your favorite sport if you wear special glasses or goggles.
Avoid make-up for a month.


Are both eyes operated at the same time?
Because it is an intraocular procedure, I prefer to operate each eye one week apart. I believe it is safest for the patient.



Will I use glasses after the operation?
The improvement in quality of life after the operation is extraordinary, according to the majority of the patients.
Most patients do not need distance glasses in daily activities.
You will need reading glasses unless you have decided to have monovision or multifocal intraocular lenses.


What are multifocal intraocular lenses?
The other possibility if you do not want to depend on glasses are multifocal intraocular lenses, that can focus on different distances. A careful selection of the patient is necessary.




ABOUT LASIK SURGERY


What is LASIK?
The Excimer laser emits a cool beam of light, that is precisely programmed by the surgeon with the patient data, to reshape the curvature of the cornea and correct the diopters of myopia, astigmatism, or hyperopia.
Because the laser beam treats the inner portions of the cornea, recovery of the patient is very fast (much more than the older techniques as RK or PRK).


Is there any pain?
LASIK is nearly painless, during and after the procedure. Most patients only report some discomfort during the surgery due to the instruments used to prevent the lids from moving or blinking. The day of the operation you may feel some minor itching.


What are the post-operative restrictions?
The day of the procedure, you are requested to rest as much as possible.
You will use antibiotic eye drops for a week and anti-inflammatory for two weeks.
Rubbing your eyes is not allowed for a month and you should avoid it for six months.
You can practice your favorite sport if you wear special glasses or goggles.
Avoid make-up for a month.


Are there any risks?
Similar to any surgical procedure, there are always risks, but it is very unlikely to have any complication in LASIK.
LASIK is considered to have lower exposure to risks than wearing contact lenses. And contacts are a very safe alternative in prescriptive eyewear.
LASIK is one of the safest Ophthalmic procedures and is performed all over the world. (approved by the FDA in the USA)


How long does the surgery take?
Having both eyes corrected, you will be at the surgical suite for about 15 minutes. The laser treatment is performed usually in less than a minute, but the entire procedure takes a little longer.


I am currently wearing contacts. Do I need to do something special?
Yes!. You should remove your contacts one week prior to your pre-surgical evaluation if you have soft lenses, and one month before, if you wear rigid gas permeable lenses..
