The purpose of the study is to compare femtosecond laser-assisted capsulotomy to manual
capsulorhexis in patients with intumescent cataracts. An intumescent cataract is defined as
a cataract with a pressurized capsular bag.


Inclusion Criteria:

- Willing to undergo cataract surgery.

- Able to lie flat in a supine position.

- Able to understand and willing to sign the Informed Consent Form (ICF).

- Presenting with intumescent white cataract, with a liquid pressurized bag and a
milky, liquid cortex.

- Other protocol-specified inclusion criteria may apply.

Exclusion Criteria:

- Pregnant or lactating mothers.

- Corneal disease that precludes application of the cornea or transmission of laser
light at 1030 nanometer (nm) wavelength.

- Corneal opacity that would interfere with the laser beam.

- Presence of blood or other material in the anterior chamber.

- Hypotony or presence of corneal implant.

- Poorly dilating pupils.

- Condition which would cause inadequate clearance between the intended capsulotomy
depth and the endothelium.

- Residual, recurrent, active ocular or eye lid disease, including any corneal
abnormality.

- Any contraindication to cataract surgery.

- Other protocol-specified exclusion criteria may apply.
