Eye surgery

Eye surgery

When to operate cataract?

When the vision diminishes,
When the visual acuity and / or contrast sensitivity decreases,
If there is a difficulty in distance vision or reading,
When there is an inconvenience linked to the diffraction of light,
Before stopping activities that require some level of vision (driving, sports, leisure …)

Who operates you?

It is the surgeon that you saw during the consultation.

Cataract surgical techniques

Other surgeries of the lens

– Severe Myopia (clear lens)
Myopia may range from-0.25 to -50.diopter

Severe myopia ranges from -10 to -50 diopters

The higher the degree of myopia, the more we observe anatomical changes (extension of the eyeball with major consequences on the internal structures of the eye (choroid, retina, vitreous) that are stretched and distorted).

Beyond a certain degree of myopia, the Excimer laser can no longer be used as it diminishes the corneal thickness.

The lens can be replaced and in this case there is no power limit since the power of a monofocal implant can be chosen. In some cases, the clear lens can be removed and a multifocal implant can be placed in the sac. It will allow a near and far distance vision.

Dislocation / ectopia of the lens

Excimer laser refractive surgery

(see Refractive surgery)

Myopia
Hyperopia
Astigmatism
Presbyopia
Presbyopia by corneal surgery

Techniques:
– Lasik
– PKR
– Epilasik (Photo Refractive Keratectomy)
– Lasek

Refractive implants

These implants are used in order to offset high refractive errors. Anterior chamber implants (clipped to the iris) or posterior chamber implants (between iris and lens) can be used.

Corneal surgery

Transfixing keratoplasty
Lamellar keratoplasty
Anterior lamellar
Posterior lamellar
Endothelio-Descemet’s transplantation (DSAEK), thin or ultra thin.
Cross-linking

Retina and vitreous


Retinal detachment:
Age Macular Degeneration
Diabetic Retinopathy
Pre-retinal membranes
Retro-retinal membranes
Retinal vein occlusionretine3

Techniques:
Vitrectomy
Laser endophotocoagulation
Dissection of membranes
Drug injections

Glaucoma

Techniques :
Laser and surgery

Iris

Iridectomy
Iridotomy
Plasty of the iris
Anomalies of the iris

Strabismus

Définition :A disorder in which the eyes diverge or converge.

Treatments: Eye realignment by vision therapy, occlusion in children, surgery.

Intervention : Moving the insertions of extraocular muscles or shortening of the muscles.

Note: When the rehabilitation methods are not sufficient.

Results: Very good if both eyes have a similar vision.

Organization:
Refractive balance,
Orthoptic checkup,
Anesthesia consultation,
Ambulatory surgery,
Usually an orbital local anesthesia
Intervention on one or both eye muscles at the same time if the deviation is significant. Further intervention is possible.
Refractive procedure can be done to rebalance the eye if the difference is significant.
