OPHTHALMOLOGICAL CLINIC SPECIALISING IN ICL INTRAOCULAR LENS IMPLANTS
REFRACTIVE SURGERY WITH IMPLEMENTATION OF ICL LENSES
It is a state-of-the-art technique that leads to immediate and excellent results.
The intervention is minimally invasive and consists of introducing a flexible intraocular lens between the iris and the lens (in front of the lens), by an incision of less than 3 mm, with topical anaesthesia (drops). It is painless, with an approximate duration of about 10 minutes for each eye. Does not require hospital admission.
Up until now, the lenses that were used were rigid, which involved making a larger incision, 6-7 mm, with the subsequent need to use 3-4 stitches to close the incision. This required local or general anaesthesia, induced high astigmatism and delayed visual recovery. Currently with ICL lenses this has changed, as discussed at the beginning of this section.
A few years ago it was advised that this this technique should be used for patients who are not able to undergo excimer laser (LASIK) treatment.
Currently, we are implanting more and more phakic lenses, since they have certain advantages compared to to laser treatments, especially in high myopia. It improves the quality of vision and is a totally reversible process. These factors make this option more appealing to many patients.
There are phakic lenses for myopic as well as hyperopic lenses, and with the ICL lens, astigmatism can be corrected at the same time. The lens requires a minimum of space inside the eye where it can be placed. This space called anterior chamber (space that exists between the cornea and the lens) is, most of the time, greater in myopic than in hyperopic. This is why most myopic patients can opt for this type of refractive surgery.
1. IN WHAT CASES IS THE INSTALLATION OF ICL LENSES ADVISED?
For young patients (between 21 and 40 years) with high myopia, hyperopia or astigmatism, thin corneas, or poor vision despite optical correction. Better results will be achieved with the implantation of a flexible epicapsular lens to correct the refractive defect, than with the use of the LASIK technique.
INDICATIONS AND CONTRAINDICATIONS
Anyone over 21 years of age who has a high refractive error that has not changed significantly during the least year, be it myopia, hyperopia and / or astigmatism. Also those patients who for any reason are not suitable for the LASIK technique.
Patients wearing contact lenses should stop using them 7 days before the preoperative exploration if it is a soft contact lens and 10 days before if it is a rigid contact lens. Before surgery you only have to go 3 days without them.
People with significant eye diseases such as cataracts or uveitis will not be operated on. Pregnant women are not suitable for this surgery, because during pregnancy there may be changes in the prescription.
2. HOW IS THE ICL LENS IMPLANTED?
The ICL lens allows the implantation of an intraocular lens using the following steps.
- The first step is to disinfect the area that will be operated on.
- We prepare the surgical field and proceed to anaesthetise the area through the topical use of drops. We do not need any other type of anaesthesia in most of our surgeries.
- The ICL is placed in an injector capable of passing the lens through a 2.8 mm incision.
- A cannula with anaesthetic solution is introduced into the anterior chamber.
- Subsequently, a dense substance (hyaluronic acid) is introduced in order to allow the anterior chamber to be able to manoeuvre with sufficient safety.
- The injector is placed over the edge of the incision to inject the ICL into the interior of the eye.
- With the help of a manipulator, the ICL is placed in the desired position with the haptics behind the iris.
- All possible remains are cleaned, through an irrigation-aspiration cannula connected to the phacoemulsifier.
- The incisions are self-healing without the need for stitches.
- Antibiotic and anti-inflammatory drops are instilled.
3. WHAT ARE THE GENERAL CARE INSTRUCTIONS AFTER REFRACTIVE SURGERY?
After refractive surgery with the implant of intraocular lenses you must follow these instructions.
It is advisable to let a few days pass between the surgery of one eye and another.
Recovery after surgery is fast. In most cases, the patient recovers within two days.
This type of lens, like the rest, does not degrade, the materials used are always biocompatible and, therefore, there is no reaction of the organism towards them.
INSTRUCTIONS AND CARE AFTER SURGERY TO IMPLANT ICL LENSES.
IN TERMS OF TREATMENT
- Wash your hands carefully before putting in any eye drops.
- If they work together, you can put two kinds of eye drops in at the same time. Just wait a minute in between inserting each one.
- Once opened, do not use any eye drops for more than four weeks without buying a new bottle. Do not forget that some must be kept in a refrigerator (this is always indicated on the product packaging).
IN TERMS OF ACTIVITIES
- You can go about your normal life and keep your eye uncovered.
- It is important that you do not rub your eyes.
- You can wash your head and face. Soft soaps used for babies are recommended. Be careful and make sure you dry yourself gently afterwards and avoid touching the eye.
- Do not cover your eye, even if it is more comfortable for you. The risk of infection increases with a covered eye. Occasionally, your ophthalmologist may recommend that you use an occluder at night.
- You can use sunglasses to go outside, especially during the first weeks after the operation. Not only will they serve to protect the eye, but they will avoid glare, which is common after the surgery.
- Unless your ophthalmologist advises you differently, you can sleep in any position that you like. Although during the first five days it is advisable not to sleep on your stomach.
- It is advisable not to use make up on your eyes for 1 month.
