Abstract
The present disclosure concerns a tuneable ophthalmic lens (100; 300) comprising a central chamber (108; 308). The ophthalmic lens (100; 300) also comprises a first fluid reservoir (106; 306) in fluid communication with the central chamber (108; 308). The first fluid reservoir (106; 306) contains a first fluid (106a; 306a) of a first refractive index. The ophthalmic lens (100; 300) further comprises a second fluid reservoir (110; 310a) in fluid communication with the central chamber (108; 308). The second fluid reservoir (110; 310) contains a second fluid (110a; 310a) of a second refractive index. At least one fluid reservoir (106, 110; 306, 310) includes a pumping mechanism (358) for pumping each of the first and second fluids (106a, 110a; 306a, 310a) between the central chamber (108; 308) and the first and second fluid reservoirs (106, 110; 306, 110) respectively. The first and second fluids (106a, 110a; 306a, 310a) are immiscible.
Claims (19)
1. A tuneable ophthalmic lens comprising: a central chamber; a first fluid reservoir in fluid communication with the central chamber, wherein the first fluid reservoir contains a first fluid of a first refractive index; and a second fluid reservoir in fluid communication with the central chamber, wherein the second fluid reservoir contains a second fluid of a second refractive index; wherein at least one of the fluid reservoirs includes a pumping mechanism for pumping each of the first and second fluids between the central chamber and the first and second fluid reservoirs respectively; and wherein the first and second fluids are immiscible.
2. A tuneable ophthalmic lens as claimed in any preceding claim, wherein when the ophthalmic lens is in use on an eye, the first fluid reservoir is located above the central chamber, and the second fluid reservoir is located below the central chamber.
3. A tuneable ophthalmic lens as claimed in any preceding claim, wherein the first fluid reservoir and the second fluid reservoir are located on opposite portions of a circumference of the central chamber.
4. A tuneable ophthalmic lens as claimed in any preceding claim, wherein each of the first and second fluid reservoirs include a pumping mechanism.
5. A tuneable ophthalmic lens as claimed in any preceding claim, wherein the pumping mechanism is an osmotic pump.
6. A tuneable ophthalmic lens as claimed in any of claims 1 to 4, wherein the pumping mechanism is a mechanical pump.
7. A tuneable ophthalmic lens as claimed in any preceding claim, wherein the pumping mechanism is located at an entrance to the central chamber.
8. A tuneable ophthalmic lens as claimed in any preceding claim, wherein the central chamber includes a structure having a refractive index and forming a Fresnel lens, wherein the first or the second refractive index is the same as the refractive index of the structure.
9. A method of tuning an ophthalmic lens, the ophthalmic lens comprising: a central chamber; a first fluid reservoir containing a first fluid of a first refractive index; and a second fluid reservoir containing a second fluid of a second refractive index, the steps comprising: pumping the first and second fluids between the first and second fluid reservoirs and the central chamber, to achieve a selected lens power.
10. A method as claimed in claim 9, further comprising the step of determining a required ratio of first to second fluid in the central reservoir.
11. A method as claimed in claim 10, wherein the required ratio is pre-calibrated for the selected lens power.
12. A method as claimed in any of claims 10 or 11, wherein determining the required ratio is performed by a processor external to the ophthalmic lens.
13. A method as claimed in claim 12, further comprising the step of: receiving an instruction, the instruction being received by the pumping mechanism and the instruction being sent by the processor, the instruction comprising the required ratio.
14. A method of manufacturing a tuneable ophthalmic lens according to any of claims 1 to 7, the method comprising the steps of: forming a first lens portion; forming a second lens portion; forming a central chamber, a first fluid reservoir, and a second fluid reservoir; and bonding the second lens portion to the first lens portion, to form the tuneable ophthalmic lens; wherein at least one of the fluid reservoirs includes a pumping mechanism, and wherein each of the first and second fluid reservoirs are in fluid connection with the central chamber.
15. A method as claimed in claim 14, wherein forming the central chamber comprises forming a recess on the second lens portion.
16. A method as claimed in claim 15, wherein forming the central chamber, the first fluid reservoir, and the second fluid reservoir comprises forming a plurality of recesses on the second lens portion.
17. A method as claimed in claim 15 or 16, wherein the second lens portion is plastically deformed.
18. A method as claimed in any of claims 15 to 17, wherein the recess/recesses are at least partially filled with fluid prior to the bonding step.
19. A kit of parts comprising: (a) a tuneable ophthalmic lens as claimed in any of claims 1 to 8, the lens including a communication module; and (b) a control module for communicating with the communication module.
