The advantages of surgery with intraocular lens

Ophthalmology has evolved in recent years, both in technological advances and in surgical techniques. One of these advances is in the field of Intraocular Lens. In fact, today they are one of the most important elements in the ophthalmological field.

Intraocular Lenses were first described by ophthalmologist Nicholas Harold Lloyd Ridley; he noticed the resistance of the eyes of the pilots of World War II. These soldiers had the carcass that surround the planes broken and fragments were inserted into their eyes. Harold Ridley discovered that these fragments were well tolerated by the eye and had the idea of creating an intraocular lens that could be inserted inside the eye to correct for diopters.

How has the intraocular lens evolved?

Initially we worked with large lenses that were quite rigid, but later the technological evolution has made these lenses can be foldable and, in this way, allow us to enter the eye through small incisions.

In parallel they have also been evolving materials. We started with rigid methacrylate lenses, which happened over time to be silicone lenses. Nowadays, we are working with totally biocompatible acrylic materials.

At the same time we have also advanced in the properties that this lens has. In the beginning the lenses were monofocal and only allowed to correct the graduation from afar. For many years we have used multifocal lenses, which are able to correct both far and near graduation.

Previously we used lenses refractive and, currently, diffractive lenses. First there were bifocal lenses, and today we have trifocals, which are used for near vision and intermediate vision. In addition, there are also extended range lenses for a more dynamically active vision.

All these advances allow us today to customize the surgery of the lens, so that we can offer the patient an implantation of intraocular lenses that adjust more to their vital needs.
