Refractive lens exchange<\/span><\/span><\/h4> <\/span> <\/div><\/div>[vc_column_text]Lens surgery<\/strong>, whether in the context of refractive surgery of the clear lens or cataract surgery, is systematically accompanied, with some exceptions, by the placement of an intraocular implant intended to replace your lens. This implant carries optical power, just like glasses or pre-corneal lenses.<\/p>\n![\"\"](\"https:\/\/www.drvincentqin.be\/wp-content\/uploads\/2023\/03\/Multifocal-1.jpg\")

The classic implants are the monofaux implants, that is to say they make it possible to compensate for myopia or preoperative hyperopia of the patient. Patients usually see well without glasses from a distance, but should wear corrective lenses for presbyopia and possibly residual astigmatism. Monofocal implants are supported in Belgium by INAMI social security as part of cataract surgery.<\/p>\n
However, there are also more sophisticated implants, correcting other visual defects, such as astigmatism or presbyopia.<\/p>\n
\u200bToric implants<\/strong>
\nToric implants make it possible to compensate for the astigmatism linked to the cornea, that is to say its anomalies in curvature responsible for distortions of the retinal image at all distances. The correction by the implant of such a visual defect makes it possible to improve vision without optical correction associated with a given distance, thus making it possible to avoid wearing corrective lenses, by far in most cases. These implants require positioning along a very precise axis, evaluated during the preoperative examination. However, such an implant may not be placed in the event of certain operational incidents.
\nThe correction of astigmatism by the implant may be incomplete, possible complementary gestures can be proposed to improve it: surgical repositioning of the implant or refractive corneal surgery. Toric implants in Belgium are supported by INAMI when the preoperative astigmatism diopter is above 2 cylindrical diopters in the corneal plane.<\/p>\n\u200bMultifocal and multifocal toric implants<\/strong>
\nThe standard implant placed during lens surgery is said to be \u201cmonofocal\u201d, that is to say allowing focusing at a predetermined distance: far, intermediate or near. Additional correction is therefore usually necessary with monofocal implants. So-called \u201cmultifocal\u201d implants can therefore be offered to you, in order to reduce or eliminate the wearing of corrective lenses from both near and far. The optical characteristics of these implants may be slightly different depending on the model.

\n\u2013 With current multifocal implants, more than 90% of patients do not wear glasses for most of their daily life.
\n\u2013 These implants also allow a stable optical correction over time, and to correct most of the associated visual defects and in particular astigmatism for the multifocal toric implant. Their optical performance is high, which induces high satisfaction indices.
\n\u2013 Visual performance improves over time, and results are optimized by the operation of the second eye.<\/p>\nPossible disadvantages:<\/strong>
\n\u2013 Not all patients can benefit from such implants, since many ocular pathologies associated with cataracts contraindicate their use; your ophthalmologist must therefore carry out a detailed assessment aimed at eliminating any contraindications,
\n\u2013 The implant calculation (or biometric calculation) used to determine its power must be extremely precise to avoid any residual refractive defect; however, a significant refractive defect limiting the expected visual result may benefit from a secondary surgical adjustment. Non-exhaustively, the following may be offered: laser surgery of the cornea, replacement of the implant placed or the placement of a second implant in addition. Your ophthalmologist is at your disposal to explain the terms to you.
\n\u2013 In the event of an operational incident (extensive rupture of the posterior capsule), such an implant may not be placed.
\n\u2013 Exceptionally, the brain cannot get used to the new vision produced by these implants and the only possible solution is then to remove it to exchange it for a standard \u201cmonofocal\u201d implant.<\/p>\n\u2013 Certain professions or certain activities may contraindicate the multifocal implant.
\n\u2013 The halos, perceptible in the evening around light sources (car headlights,
\nstreet lights\u2026), initially present in most cases, generally fade with the
\ntime.
\n\u2013 In a very small percentage of cases, these halos can make driving at night
\ndifficult.
\n\u2013 Glare phenomena are also reported with an increase in the
\nsensitivity to light, this phenomenon diminishing after a few months, and easily compensated by
\nwearing tinted glasses.
\n\u2013 Visual tiredness is sometimes felt, linked to a moderate reduction in sensitivity
\nto contrasts. More lighting for reading activities is usually sufficient,
\nmore rarely extra glasses. Occasional glasses may also be offered during
\ndriving at night or for the computer.
\nMultifocal and multifocal toric implants generally justify an additional cost and in Belgium, they are not reimbursed by INAMI.<\/p>\n
In conclusion,<\/strong> these sophisticated implants require specific means of investigation before
\ntheir fitting, to allow great independence vis-\u00e0-vis the wearing of corrective lenses, with a
\nimproved quality of life; they can be used in first intention, but also during a
\nreoperation on a monofocal implant previously placed. The implants described in this document
\nrepresent an option and are not mandatory; surgery with monofocal implants gives
\nrule of very good results, at the cost of an optical correction by glasses more often necessary.[\/vc_column_text][\/vc_column][\/vc_row][vc_row full_width=”stretch_row_content” css=”.vc_custom_1665505883361{margin-bottom: -40px !important;padding-top: 6vh !important;padding-right: 6vh !important;padding-bottom: 6vh !important;padding-left: 6vh !important;background-color: #5abbed !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}”][vc_column width=”1\/6″][\/vc_column][vc_column width=”2\/3″]Ophthalmologist in Brussels and Namur<\/span> <\/span> CONTACT<\/span><\/span><\/h4> <\/span> <\/div><\/div>[vc_column_text basel_color_scheme=”light”]<\/p>\nYou want to make an appointment?
