IOL MASTER :
A new dimension in optical biometry to improve postoperative refractive results.

Advantages
• Precise Measuring: exact measurement of the eye is possible even in cases of high ametropia, pupil size
as well as state of accommodation.
• Non contact Technique: no requirement of local anesthesia, no risk of infection from patient to patient.
• Saves time: axial length, corneal curvature and anterior chamber depth of the patient's eye are measured
on the same instrument saving valuable time.

PAM :
Gives an estimate of potential vision following cataract surgery. The Potential Acuity Meter (PAM) is a device that is designed to project an eye chart directly onto the retina, in essence bypassing the cloudy lens. For patients with retinal disease, such as age related macular degeneration, the PAM may improve the reliability of anticipated vision following cataract surgery.

SUPER PINHOLE DEVICE
The Super Pinhole device works on a different principle, but may deliver the same result. The patient views a specialized eye chart through a pinhole in an attempt to discover a clearer region in the cataract. Both of these potential acuity measurements may overestimate or underestimate the vision achieved after cataract surgery.

TREATMENTS :
Cataracts can be removed at any age. You no longer have to wait until the cataract "ripens" or until you lose your sight before surgery can be performed. In fact the placement of an intraocular lens (IOL) implant to restore vision is best done in when the cataract starts interfering with your daily activities or causes a decrease in vision.
The clouded lens (cataract) must be removed surgically. Common type of Extra Capsular Cataract Extraction is called Phacoemulsification (often just called "phaco") which the general public understands as Laser cataract surgery.

ABOUT PHACOEMULSIFICATION
Dr. Charles Kelmen conceived and developed phacoemulsification, a method of cataract removal by ultrasonic fragmentation and aspiration of the cataractous lens through a small wound. Phacoemulsification is advantageous for both patients and surgeon. • Greater intra operative control.
• A smaller wound with no sutures possesses less risk of infection and induced astigmatism and gives better long and short term
predictability of vision.
• Patients are able to resume normal activity much sooner and with fewer restrictions than the traditional cataract surgery.
Phacoemulsification with sophisticated instrumentation provides options of pulse and burst mode.

TYPES OF INTRAOCULAR LENS

1. Monofocal lens :

These lenses are the most commonly implanted lenses today. They have equal power in all regions of the lens and can provide high-quality distance vision, usually with only a light pair of spectacles. Monofocal lenses do not correct astigmatism, an irregular oblong corneal shape that can distort vision at all distances, and require corrective lenses for all near tasks, such as reading or writing.

2. Toric lens:
Toric lenses have more power in one specific region in the lens to correct astigmatism as well as distance vision for many individuals. Due to the difference in lens power in different areas, the correction of astigmatism with a toric lens requires that the lens be positioned in a very specific configuration. While toric lenses can improve distance vision and astigmatism, they still require corrective lenses for all near tasks, such as reading or writing.

3. Multifocal lens:
Multifocal intraocular lenses are one of the latest advancements in lens technology. These lenses have a variety of regions with different power that allows some individuals to see at a variety of distances, including distance, intermediate, and near. While promising, multifocal lenses are not for everyone. They can cause significantly more glare than monofocal or toric lenses. Multifocal lenses cannot correct astigmatism, and some patients still require spectacles or contacts for clearest vision.

BEFORE YOUR SURGERY

The Night Before Surgery
Don't eat or drink anything after midnight the night before your surgery. This includes water, coffee, chewing gum, and mints. If you have been told to continue your daily medication, take it only with small sips of water. Make sure you follow any other instructions your doctor gives you.

Day of your Surgery
Have someone drive you to and from the outpatient surgery clinic or hospital. Plan to be there for about 2 to 3 hours. The surgery is brief. But the hospital staff needs a little time to get you ready for surgery. When you arrive, you may have to sign a consent form. This form explains the risks of surgery.
Just before surgery, your doctor will give you medicine that will relax you and keep you from feeling pain. You may sleep lightly.

First 24 Hours
After surgery, you'll rest in a recovery area for less than an hour. Even though you may feel fine, you should take it easy. Your doctor will let you know what you should and shouldn't do once you get home. You may need to wear eye protection the first day. Also, remember to take any eyedrops or other medicine your doctor prescribes.
