Description : Check out this medical PowerPoint presentation titled "Cataract and Implant Surgery” by Dominic McHugh, MD FRCS.

This medical PowerPoint presentation is about cataract and implant surgery.

Cataract surgery is a procedure used to remove the natural lens of the eye when it becomes cloudy due to a cataract, which can cause blurry or dim vision, and replace it with an artificial intraocular lens (IOL) to restore clear vision. The surgery is typically performed on an outpatient basis and takes about 15-20 minutes to complete.

During cataract surgery, a small incision is made in the cornea, and the cloudy lens is broken up into small pieces using ultrasound energy (phacoemulsification) and removed. The IOL is then inserted into the same location where the natural lens was, and the incision is closed with tiny stitches or self-sealing incisions that do not require stitches.

Implant surgery, on the other hand, refers to the surgical placement of an artificial device, such as a joint or a pacemaker, into the body to replace or support a damaged or dysfunctional body part. In the context of eye surgery, implant surgery may involve the insertion of an artificial lens to correct vision problems other than cataracts, such as nearsightedness, farsightedness, or astigmatism.

In summary, cataract surgery is a type of implant surgery that involves the removal of a cloudy natural lens and the insertion of an artificial intraocular lens, while implant surgery generally refers to the surgical placement of an artificial device to replace or support a damaged or dysfunctional body part.

CataractCauses Age Congenital (genetic, metabolic) Trauma Infection Inflammation Surgical Drugs (eg steroids)
Slide 3-

Cataract May be induced by surgical procedure: lens touch; gas; oil
Slide 4-

Cataract types Nuclear sclerosis Posterior subscapsular Congenital (rubella) Trauma
Slide 5-

Management of Cataract ECCE (Extracapsular cataract extraction) But longer wound healing time
Slide 6-

Cataract Surgery Small incisional Phacoemulsification surgery (Developed by Kelman, USA)
Slide 7-

Before IOL implantation was developed Aphakic spectacles Contact lenses
Slide 8-

Pioneer of intraocular lens implant Sir Harold Ridley FRS FRCS
Slide 9-

Harold Ridley collaborated with the Rayner company to develop the IOL John Pike, Rayner Company
Slide 10-

1949-1950: First IOL implants
Slide 11-

Choice of IOL Insertion through small incision High biomcompatilbility Allows good retinal view Stable centration Low PCO (posterior capsular opacification) rate
Slide 12-

IOL choiceWhy foldable/injectable?Minimise incision size to reduce healing time and astigmatism PMMA(rigid) : Non-foldable+large incision Acrylic: Injectable through 2.2-3.2 mm currently.
Slide 13-

Preparation for cataract surgery Biometry: The calculation of required IOL power Keratometry (K) (corneal curvature) Axial length (AL) of eye (ultrasound) IOL power= A constant-2.5xAL-0.9K Eg: 118-2.5x 24-0.9x45=17.5 dioptres IOL power
