Throughout life, the crystalline lens gradually loses its natural elasticity and corneal opacities can appear. For these reasons, the ULTRALASIK surgery is contraindicated.
At IRIS Ophtalmology Clinic, your optometrist and ophthalmologist will inform you of the advantages and disadvantages of the Different types of intraocular lens. They will be able to advise you on the choice best suited to your needs and lifestyle notably through replacing a clear crystalline lens with an intraocular, monofocal or multifocal lens.
During the pre-operative assessment, the optometrist and the surgeon inform you of the advantages and disadvantages of the different types of intraocular lens. They will be able to advise you on the choice best suited to your needs and lifestyle. The power and the type of lens will be carefully chosen to ensure your diminished reliance on glasses and/or contact lenses.
The options: seeing far, seeing near or both
At the IRIS Ophthalmology Clinic, the ophthalmologist has a wide range of intraocular lenses at his disposal to meet each person’s speciﬁ c needs. No type of lens is right for everyone. Your surgeon will determine the one best suited to you. There are different types of intraocular lens available: monofocal, accommodative and multifocal.
The monofocal lens provides a single focus point, that is, it allows the eye to see well at a single distance. Your optometrist and ophthalmologist can offer you different correction options using monofocal lenses:
If you decide to have both eyes corrected for distance vision, you will enjoy the best quality vision for your distance-vision activities. It’s what nature should have given you from the beginning (e.g., daytime/evening driving, watching television, going to the movies, playing sports, etc.).
However, you will have to wear glasses in order to correct your intermediate and near vision (e.g., reading books, working at a computer, cooking, reading the time on your watch, putting on make-up, shaving, performing do-it-yourself work, etc.). Progressive lenses may be necessary, even if you don’t need to wear them in order to see at a distance.
VYou can choose to have one eye (dominant) corrected for distance vision and the other (non-dominant) for near vision. This method provides an option that can reduce your dependence to corrective lenses.
Monovision may be simulated by contact lenses before surgery. It is not suited for everyone, because it requires compromises in vision quality.
Corrective lenses may be necessary to equalize vision in both eyes to improve your comfort when performing lengthy tasks requiring precision (e.g., driving your car at night, working at a computer, reading small print, etc.).
The multifocal lens uses an optical principle that allows separation of light into several focal points. This principle allows “simultaneous vision” at more than one distance at the same time, in the same eye.
In certain cases, multifocal contact lenses may help you understand or simulate the effect of a multifocal intraocular lens prior to surgery.
Multifocal lenses may suit you if you highly wish not to wear corrective lenses for both distance and near vision.
Multifocal lenses provide you with independence from glasses or corneal lens for distance and near vision.
