Anterior Segment Surgery

Intraocular lens exchange

An intraocular lens can sometimes cause issues with vision, comfort, or glare.  When more straightforward options have been tried to fix the problem and are not successful, the lens can be removed and a more suitable lens implanted.

 

Iris reconstruction

Patients with pupil abnormalities or iris defects from birth, trauma or other causes, may suffer from a varying degree of visual disability. Iris reconstruction surgery is usually achieved by through small incisions of the cornea. A variety suturing techniques are used to fix the pupil or iris irregularity.

 

Artificial iris

Artificial iris implants are used when iris defects cannot be fixed by suturing.  The color, size, and material of artificial iris implants vary.  Proper implant selection is made according to what each individual patient’s eye needs.

 

Secondary lens

Secondary intraocular lens implantation is considered when the eye’s regular support system (capsule bag, zonules) for a artificial lens is either absent or damaged by trauma or previous surgery. Without this regular support, artificial intraocular lenses can be supported in three other ways: placement in front of the anterior chamber angle, iris (anterior chamber lens), fixated to the iris, or fixated to the sclera (white part of the eye). Each technique has its pros and cons, and the most appropriate way is chosen based on the condition of a patient’s eye.

 

Risks

Risks associated with anterior segment surgery include infection, bleeding, corneal swelling, inflammation, retinal detachment/swelling, wound leak, dislocated lens, and glaucoma.
