  • Patent number: 7644603
    Abstract: A method of testing a surgical system that takes advantage of the fact that in a balanced irrigation/aspiration system (inflow?outflow) the duration of the aspiration pressure recovery to the irrigation fluid source pressure immediately following pump stop is independent of pump run time. This method provides a more reliable way of detecting restricted irrigation flow configurations not detectable by the current methods, such as marginal irrigation flow cases that could potentially lead to surgical complications (e.g. chamber collapse during post-occlusion break surge).

  • Patent number: 7640119
    Abstract: In some embodiments, a method of adjusting the amount of energy delivered to a liquefaction handpiece of an ophthalmic surgical system may include monitoring a voltage source at an output of a charging element of the ophthalmic surgical system, dynamically adjusting the charging element output based on feedback from the monitored voltage source, and dynamically adjusting the amount of energy provided by the voltage source as an input to the liquefaction handpiece. The energy adjustment may be based on the adjusted charging element output.

  • Patent number: 7625388
    Abstract: A surgical system that is able to sense the onset of an occlusion or other surgical event as well as the instant an occlusion breaks. To help avoid overheating of the tip, the system determines an approximate temperature of the eye using an irrigation flow rate and reduces the power to the handpiece automatically if an overheating situation is predicted. Alternatively or in addition, the system monitors the power drawn by the handpiece, which is indicative of the cutting load on the tip, and automatically adjusts the power or stroke of the tip to compensate for increased loads on the tip.
