Hyperopia operation
La refractive surgery laser or implanting a intraocular lens is the only option for permanently correct farsightedness and dispense with the use of glasses or contact lenses.
There are different surgical options to perform a hyperopia operation, the most indicated procedure will depend on the ocular characteristics of the patient.

What is hyperopia?
Refractive defects are disorders that cause difficulties in seeing our surroundings clearly.
La farsightedness is a refractive defect that takes place when the light that enters our eyes is projected behind the retina and not on it, causing blurred vision of objects at close range.
This visual disturbance occurs because the eye is smaller than normal, lens power is low or the cornea has less curvature than normal. Hyperopia may be present from birth.
Sometimes farsightedness can be confused with presbyopia because both conditions cause blurred near vision, But they are not the same. The farsightedness is the cause of the projection of the light behind the retinaWhile presbyopia is atrophy, because of age, focus mechanisms Of the eye.
Symptom
El main symptom of farsightedness is difficulty seeing closely. However, this refractive defect can also cause other discomforts such as:
- Headache after reading or writing.
- Visual fatigue.
- Eye pain.
- Squinting to see clearly.
- Burning eyepiece.
Hyperopia operation
Hyperopia operation is the only option currently available to permanently eliminate the use of glasses or contact lenses. To carry out the intervention, we have different surgical options: laser refractive surgery (FemtoLasik, LASIK y PRK) or by implementing a intraocular lens.
The hyperopia operation consists of molding any irregularity in the cornea so that the light is projected onto the retina.
The goal of surgery is correct the refraction of the hyperopic eye through a laser specialized called excimer.
FemtoLasik
La laser refractive surgery FemtoLasik it is the most novel and safe that exists todaybecause it allows operate farsightedness entirely with laser technology.
At the beginning of the surgery, it is applied femtosecond laser, a modern and very precise laser that allows the corneal tissue to be separated into layers. Then it is applied excimer laser to correct the cornea.
By using femtosecond laser we reduce intraoperative risks, postoperative recovery is faster and we can operate corneas very thin in patients with morphologies eyepieces discounts.
LASIK
La laser refractive surgery Lasik It is the most widely used technique today to operate on vision defects.
It consists of making a corneal flap by the use of a special blade (microkeratome) to modify the cornea later with the excimer laser.
After correction, the flap is put back into place no need for sutures.
PRK
Refractive laser surgery PRK is first laser technique used to correct refractive defects and it is still in force.
The procedure consists of remove the corneal epithelium, the most superficial layer of the cornea, by scraping for then apply excimer laser and modify the imperfections of the fabric.
After surgery, the epithelium regenerates on its own. Of course, the patient must use some therapeutic lenses special during the postoperative period and until the specailista considers it appropriate.
Intraocular lens
La Hyperopia operation by implanting an intraocular lens we do it in those people who your cornea does not allow laser intervention.
La refractive surgery with intraocular lens it consists of making a small incision in the eye to inject a lens designed specifically for that patient. The lens is placed behind the iris and ahead of the lens and will make the function of a contact lens.
It is a very surgery safe and predictable but that requires a high level of specialization.
Refractive surgery is a safe procedure that is carried out under the influence of a local anesthesia applied in drops, aproximately last 15 minutes for each eye and it is ambulatory. After surgery, the patient can go home free of glasses or contact lenses.
During the postoperative period it is important to comply with all medical indications and to attend the check-ups with the ophthalmologist.
What is?
El objetivo the refractive surgery to treat farsightedness It is to totally eliminate the graduation that the patient presents before performing the intervention.
Thanks to the modern surgical techniques that we apply today and laser platforms that we use in our center, we are able to eliminate, during hyperopia surgery, the dependence on glasses or contact lenses in patients who present the following refractive defects.
Myopia
Myopia is a refractive error that occurs when a person sees distant objects blurry but can see nearby objects correctly.
Farsightedness
Farsightedness manifests itself when a person cannot see objects that are close by clearly but can see those that are at a certain distance.
Astigmatism
Astigmatism occurs when the surface of the cornea is irregular. Resembling the wavy mirrors of amusement parks.
Who is a good candidate for the operation?
To to know if a person is a candidate for hyperopia surgery, you need to go to an ophthalmological consultation.
Through an eye examination and the specific tests we perform to assess the intervention, the doctor will be able to determine if the patient meets all the requirements for refractive surgery.
The variety of requirements for hyperopia are:
- Have more than Age 18.
- Having the same graduation for at least one year.
- Have good eye health.
- Not be pregnant or in process breastfeeding.
The eyeball is a structure that develops progressively and completes its development when the person reaches 18 years of age.
For this reason, before refractive surgery, it is important for the medical specialist to verify that the eyeball has reached its maximum size.
If hyperopia were to be operated on in a developing eyeball, it is very likely that diopters will increase after surgery and the patient will be hyperopic again.
Individualized prior study before surgery
Before the hyperopia operation, it is important to go to the ophthalmologist to thoroughly examine the ocular structure, determine if you can opt for refractive surgery and know the best technique to correct the visual defect.
During this examination, the doctor will perform a series of exams to check the state of eye health:
- Measurement of intraocular pressure.
- Visual acuity and graduation of vision.
- Study of the anterior and posterior segment of the eye.
- Ocular biometrics.
- Corneal topography.
- Aberrometry.
- Corneal pachymetry.
What if I have farsightedness and astigmatism?
Having astigmatism and farsightedness at the same time It's very common And fortunately, both defects can be corrected at the same time by refractive surgery.
La operation of farsightedness and astigmatism it is also carried out with laser techniques (FemtoLasik, LASIK and PRK) or by implanting an intraocular lens.
After an operation for farsightedness and astigmatism, patients get excellent results and can dispense with the use of glasses and contact lenses.
Postoperative
El postoperative period of hyperopia operation it's very simple if follow the instructions to the letter that the surgeon has previously scheduled the intervention.
Once the intervention has ended, the person remains for a few minutes in a recovery room with his eyes closed. Then the surgeon check the state of the eyes and make sure everything has gone perfectly. During this time you may feel discomfort in the eye, as if you had grit inside them.
On the same day of the intervention the person leaves home and with the passing of the hours the sensation of having a foreign body in the eyes will disappear.
La incorporation into normal life is very fast and the improvement of sight becomes more and more evident with the passing of days and weeks. It is important comply with medication, the rest and use of artificial tears as the doctor has prescribed.
