LASIK MD Laser Eye Surgery – Bausch
& Lomb Zero Compression Keratome
LASIK MD was the first clinic in the world – and one of the few laser eye centres in Canada – to offer this new technology for laser vision correction. This is the latest Bausch & Lomb technology which saves corneal tissue through thinner, smoother and more uniform flaps. It also offers a high degree of safety that is gentle on tissues avoiding many surface complications. Most important, this new technology creates excellent quality flaps, making this step a safe component of LASIK surgery.
Who should use it?
-
Patients who desire the most recent techniques in keratome technology
-
Patients with high prescriptions, thinner corneas and very large pupils who would benefit from saving corneal tissue
-
Patients who are prone to corneal swelling (corneal dystrophy)
-
Patients with delicate surface skin on the cornea
Bausch & Lomb Zero Compression Keratome and Corneal Abrasions
The Zero Compression Keratome is a device used during LASIK vision
correction to decrease the occurrence of corneal epithelial
abrasions (“scratches”). This new and improved version
of the
Bausch & Lomb Hansatome offers significant benefits to
patients. There is a decreased risk of corneal abrasions. In
addition, thinner flaps can be created for patients with thin
corneas, large pupils or high prescriptions.
When comparing the standard Bausch & Lomb Hansatome and the Zero Compression Keratome (ZCK), ZCK significantly reduces the incidence of abrasions (as demonstrated by Table 1.1).

Corneal abrasions increase the chance of other complications, such as inflammation (50%), epithelial in-growth (10%), flap swelling (50%) and flap wrinkles (10%). However, without corneal abrasions, the chance of the latter complications decreases to less than 1% and occurrences of inflammation decreases to between 1% and 2%.
