Systems and methods for delivering light to a surgical site
View Patent ↗An ophthalmic surgery system for delivering light to a surgical site includes an ophthalmic surgical console including a light source to generate light and a processor operably coupled to the light source and a surgical handpiece operably coupled to the ophthalmic surgical console via an optical fiber for delivering light from the from the light source to a surgical site. The processor is configured to adjust the light source to ensure an output light level at the surgical site is substantially consistent over a period of time.
1. An ophthalmic surgery system for delivering light to a surgical site, the ophthalmic surgery system comprising:
an ophthalmic surgical console including a light source for generating light and a processor operably coupled to the light source; and
a surgical handpiece operably coupled to the ophthalmic surgical console via an optical fiber for delivering light from the light source to a surgical site, the processor being configured to adjust the light source based on at least a change in transmissivity of the optical fiber to ensure an output light level at the surgical site is substantially consistent over a duration of an ophthalmic surgical procedure.
2. The ophthalmic surgery system of claim 1 , wherein the processor is configured to adjust the light source, based on at least one property of the light source.
3. The ophthalmic surgery system of claim 2 , wherein the at least one property includes an age of the light source.
4. The ophthalmic surgery system of claim 1 , further comprising a memory operably coupled to the processor, the memory including a plurality of fiber transmissivity factors, the processor configured to adjust the light source as a function of at least one of the plurality of transmissivity factors.
5. An ophthalmic surgery system comprising an ophthalmic surgical console including a light source to generate light, a processor, and a memory operably coupled to the processor, a surgical handpiece operably coupled to the ophthalmic surgical console via an optical fiber for delivering light from the light source to a surgical site, and a program stored in the memory and executable by the processor for adjusting the light source based on at least a change in transmissivity of the optical fiber stored in the memory to ensure an output light level at the surgical site is substantially consistent over a duration of an ophthalmic surgical procedure.
6. A method of delivering light from a light source of an ophthalmic surgical console to a surgical site via an optical fiber, the method comprising:
identifying an output light level at the surgical site;
providing a processor configured to calculate a command light level based on at least a change in transmissivity of the optical fiber; and
adjusting the light source according to the command light level to ensure the output light level is substantially consistent over a duration of an ophthalmic surgical procedure.
7. The method of claim 6 , wherein adjusting the light source includes calculating a command light level, based on at least one property of the light source, and adjusting the light source according to the command light level.
8. The method of claim 7 , wherein the at least one property of the light source is an age of the light source.
9. The method of claim 6 , wherein adjusting the light source includes calculating a command light level, as a function of at least one of a fiber transmissivity factor, an age factor, and an attenuation factor, and adjusting the light source according to the command light level.
10. The method of claim 9 , wherein calculating a command light level includes periodically calculating a command light level.
11. The method of claim 6 , wherein adjusting the light source includes periodically adjusting the light source.
