Retinal Surgery: removal of an epiretinal membrane (scar tissue on the surface of the retina) подробнее
Some patients may develop scar tissue on the surface of the retina called Epiretinal membrane or ERM. The membrane often builds up slowly over time and may contract to cause wrinkling of the retinal surface leading to distortion of vision. The scar tissue can be removed via a surgery called “vitrectomy” which involves removing the gel inside the eye using very small instruments. Then the membrane is peeled off the retina with the aid of fine micro-forceps. When the membrane is removed by surgery, you will usually notice an improvement in vision, particularly in the quality of vision. This usually takes a few weeks to months to reach the final improvement as the retina heals after the surgery. You will be followed with the aid of retinal scans to monitor the healing process and restoration of the retinal layers.
Cataract surgery and congenital iris coloboma repair - Single-pass four-throw pupilloplasty подробнее
This is a case of congenital iris coloboma and large chorioretinal coloboma. The patient developed a +2 cataract and experienced drop in her vision(55yrs, single eye, iris + lens coloboma, about 2 clock hours of zonular dehiscence, large chorioretinal coloboma, Biometry +32, other eye has early phthisis).
Combined cataract surgery & Iris coloboma repair (using Single-pass four-throw pupilloplasty using 10/0 prolene) was performed to avoid the prismatic effect of the lens edge. I prefer to do an initial gentle stretch of the iris tissue to assess the gap + to take good bites in the iris tissue to avoid cheese-wiring (in these cases there is a gap in the iris tissue, and any repair will require some amount of iris stretch). When possible, try to preserve the geometric centre of the pupil.
Toric lens implants for patients with corneal astigmatism подробнее
Toric lenses are suitable for patients with corneal astigmatism. Astigmatism is a condition when the cornea, the front part of the eye, is like a rugby ball rather than a sphere. Toric lenses can correct astigmatism in the prescription. When a patient has a significant degree of astigmatism, a toric lens would be beneficial to help spectacle independence.
These lenses have special marks at the axis of the astigmatism.
They require careful pre-operative planning of the level of the astigmatism. They are inserted inside the eye after careful marking of the astigmatism meridian on the cornea and the lens is aligned along this desired meridian.
