This term refers to any type of surgery involving the lens of the eye, such as cataract; the cornea (transparent window of the eye), the iris (colored portion with central hole) or the drainage structures (angle of the eye).
Many of these eye conditions can be inherited or trauma can affect the iris or lens and require medical or surgical correction. In addition, some patients may have had a complication from a previous cataract surgery, requiring additional anterior segment surgery to improve visual outcomes. Even after uncomplicated surgery, some patients may experience blurry vision, visual distortions, or aberrations secondary to the intraocular lens placed in the eye, requiring a lens exchange to improve vision.
Dr Michael Spencer has performed a wide range of anterior segment surgery, including cataract surgery (both standard and complex), intraocular lens exchange after previous cataract surgery, management of dislocated intraocular lenses, secondary intraocular lens placement, and iris repair or iris replacement.
Cataracts refer to the natural clouding of the native lens that sits inside the eye, behind the iris (the colored part of the eye).
This surgery is performed when visual acuity is not as expected, or if the patient experiences severe visual aberrations (such as glare, halos, or starburst) that have not improved with time or responded to more conservative measures
Sometimes the iris may be damaged (as can occur with trauma or previous surgery) or patients are born with defects in their iris. In these types of cases, the surgeon may offer a form of iris surgery to the patient.
The drainage angle is the point in the eye where the colored part of the eye (iris) and the white covering over the eye (sclera) meet. This is where fluid within the inner eye (which is different from tears that lubricate the eye’s outer surface) drains.
