Hyperopia Laser Surgery
Through the correction of hyperopia using the Femtosecond laser Lasik method, patients can see clearly both far and near, quickly and efficiently. Surgery only lasts a few minutes and the vision is restored immediately.
Hyperopia Laser Surgery using the Femtosecond Laser Lasik method.
Our Same Day Clinic is equipped with the state-of-the-art Femtosecond laser suite, where a pulsing laser creates a high precision flap, without using a blade, to then correct the cornea’s curvature.
The accuracy and safety of this method along with the patient’s comfort make the Femtosecond laser Lasik method the most modern solution for the correction of hyperopia using laser surgery.
Both international literature and our clinic’s statistics show that in up to 20% of patients who undergo hyperopia correction surgery there is a regression of up to 1/3 of the original correction.
Preoperative Evaluation for Hyperopia Laser surgery
The preoperative evaluation is the cornerstone for the success of the hyperopia laser surgery. During the preoperative evaluation, all the required data is collected to allow the refractive surgeon to determine if the patient is a good candidate for laser surgery to correct hyperopia.
The preoperative evaluation for hyperopia laser surgery includes:
- History taking for patient and their family. The patient’s history needs to be detailed and accurate. Any current and past diseases and medications need to be recorded, as does the existence of allergies. Furthermore, any previous surgeries or medications and conditions that may affect the healing of the corneal wound must be recorded.
- Ocular history taking. After personal and family history taking, the patient’s ocular history is taken, and any eye preparations the patient is taking or has taken in the past are recorded. The candidate is asked if they used to wear glasses, when they started wearing glasses and if they have ever worn contact lenses. Contact lenses may alter the shape of the anterior surface of the cornea and, therefore, patients must avoid wearing them both during the preoperative evaluation and prior to surgery.
- Visual acuity test. Determination of the candidate’s exact refractive error during the preoperative evaluation also determines the amount of the corneal stroma which needs to be removed to achieve the desired post-operative result. For this reason, our personnel are fully acquainted with the refractive error termination test; furthermore, the operating condition of the equipment used needs to be regularly checked.
Testing of pupillary responses and pupil diameter. Measurement of the pupil’s diameter is performed in scotopic conditions since there is an increased chance of visual problems at night if the diameter of the scotopic pupil exceeds the ablation zone.
- Intra-ocular pressure. The measurement of the intra-ocular pressure is performed after the refraction and the mapping of the cornea, so that any deformity of the cornea’s anterior surface resulting from contact with the applanation tonometer will not affect the preoperative measurements. Refractive surgery is counter indicated for patients with uncontrolled glaucoma, patients who take many medications or who require surgery to control intraocular pressure, or patients with advanced glaucoma, significant cupping of the optical cavity and concomitant scotomas in the examination of fields of view.
- Slit-lamp. The slit-lamp exam is an integral part of the pre-operative evaluation. Eyelid examination reveals the existence of blepharitis or any other conditions. Moreover, the tear film quality, the anterior chamber and the iris are assessed.
- Cornea imaging. The curvature and the shape of the cornea can be evaluated using various cornea imaging methods, such as systems based on Placido’s disk or steepening of the cornea.
- Pachymetry. The thickness of the cornea is a decisive factor when screening for candidates for a hyperopia laser surgery.
Informing the patient. After the full patient evaluation is complete and if it is determined that the patient fulfills the safety criteria for undergoing hyperopia laser surgery, the patient is fully and thoroughly informed and is requested to fill in a consent form.
