Another possibility to consider is that only the anterior segment of the eye is damaged: no lens, no iris, no cornea, no vitreous. No worries! Here's the procedure as I see it.
We have the funds. . . We have the technology. . . We can rebuild!
Since we're 200 years in the future, I'll posit some things a little in advance of what we can do now.
Introduction
Due to advances in bio-mechanical material & artificial tissue science, we're able to coat a technological device with a kind of immune-transparent tissue, composed of lab-grown and host-derived components. Rejection is impossible. The implant is secured within a bony~cartilagenous~connective tissue matrix that effectively seals and secures it within the host's body.
The implant itself is based on centuries old technologies, applied in a new way: lasers, the IMT & the IOL, the latter two of which serve to replace the biological lens as a light focusing device. Our device, the INTROCULUS ITVS (the Intraocular Total Vision System) comprises three essential functions and several variable ancillary functions.
Of course, central vision & peripheral vision are keys. Much like the IOLs of old, the ITVS focuses incoming light onto the biological retina, allowing the Cyborg to "see normally". In addition to normal colour vision, the ordinary lens system allows for "normal" low light vision. What distinguished the ITVS from the competition is the rest of the story: we've known for centuries that, apart from standard colour vision, humans are able to see and process UV and IR light as well. ITVS takes advantage of this ability: when the Cyborg engages IR-Vision, incoming IR radiation is translated into ultra rapid IR laser bursts that the retina can see; when the Cyborg engages UV-Vision, the nano-computer shunts the UV light signals to predetermined parts of the retina in succession, allowing the Cyborg full UV vision without the side effects encountered by unaltered humans.
Procedure
Preparation, Phase I: Neuro-Ophthalmology team will address the remaining portions of the globe and prepare them for implantation. Remaining vitreous & any foreign bodies are removed; ocular muscles are disinserted; edge of the globe is prepared by excising non-viable tissue and repairing tears with standard adhesive techniques; the retina and inner surfaces of the globe are scanned and measured in the minutest detail, down to the atomic level in the case of the nerve receptors within the retina; finally a biopatch device, which is basically a biological bandaid, is trimmed and secured to the globe-stump.
Preparation, Phase II: Cranio-Maxillo-Facial team will address all aspects of repairing facial fractures, in consultation with Plastic-Reconstructive team. Particular attention will be paid to the preparation of the orbital bone structures. CMF team will take 3D measurements of the bony orbit and surrounding bony tissues. Plastics will secure tissue samples for Rapid Growth Autoreimplantation. (Basically, they'll take some skin and connective tissue & fat cells for directed cloning & tissue development: the Cyborg will end up with a natural appearing face, eye lid, etc.
Preparation, Phase III: Neuro-Ophtho team in conjunction with CMF will review the gathered measurements and begin the process of 3D tissue extrusion of the ITVS skeleton. The ITVS skeleton is the latticework into which the non-biological device will be housed. Precise measurement are required in order to calibrate & aim the data stream from the device to the retina. Measurements will be sent to the Introculus.co labs where bespoke devices will be built to the CyberForce general command's specifications for this unit. Each device is tailor made for an individual cyborg, with tolerances of less than .001mm (physical dimensions) and 1:1 concatenation between device signal output device and its designated array of biological optic nerves.
Implantation: Once all the devices, Introculus Bio-Skeletons and tissue packs are ready, all teams will converge for implantation.
Plastics will open the face and remove the external tissue bandages. CMF will prepare the orbital bone for the skeleton implant while N-O connects the device to its biological housing. Preparation of the orbit involves precise alignment of the Introculus Drill Gantry, a device that bores all fastener holes and reams out all areas of native bone where the implanted Skeleton will reside. They will also reserve the removed bone dust & blood for use later.
N-O will now remove the biopatch device from the prepared edge of the globe and secure the exterior of the globe to the first part of the Skeleton. This is a simple 3D extruded bio-lattice that, with "bioglue technology" supports & holds the soft globe in a predetermined attitude and position, based on measurements taken earlier. The posterior portions of this bio-lattice will be filled by Plastics with lab generated orbital fat tissues which will, as with the original human tissue, serve to protect the remaining globe of the eye and the optic nerve. It also serves to "fill up the space" in the orbit. N-O will come in again to prepare the power filaments: fine bio-neutral wires that will convert physical movement (whether from facial muscle movement to the rhythmic motion of the tiniest of arterioles) into electrical energy and thence convey that energy to the ITVS device, which will then be fully powered.
Once the bio-lattice Skeleton is in place, N-O will simply slide into place the ITVS device within its housing. Again, bioglue technology will be used to seal the two halves of the Bio-Skeleton together: the engineered tissue surrounding the housing & device will bond seamlessly with the tissue of the retina. The seal will allow NuVit, an optically enhanced clear fluid vitreous humour replacement system, to fill the space that was once the man's posterior chamber.
Once the device is placed, Plastics will once again take over. The once barbaric procedure known to history as the "microsurgical free flap" is now perfected in the form of a nano-surgical autologous facial flap. Essentially, the man's own tissues have been rapidly engineered to replace the temporary "bandaid" tissues. Nano-lasers and microscopically controlled instrumentation assures that an adequate blood supply is routed to the new tissue. Bioglues and tissue regeneration techniques allow for the flap to be perfectly trimmed & inset within two hours and initial tissue fusion to occur within the first post-operative day.
Conclusion
Post-Operative Healing: Various modern techniques are used to ensure rapid and biologically integral healing of tissues & bonding with bio-engineered components. Continuous monitoring of blood levels of oxygenation & tissue regeneration factors (both systemically & locally at the flap locations) alert Nursing & Medical well in advance of a crisis. Flap death is now a very rare artifact, with incidence less than 0.5% Of more concern is the mental state of the host as his levels of consciousness waxes and wanes after surgery.
Post-Operative Therapy: As with any bio-technological implant, a Cyborg must undergo a rigorous programme of post-operative training and therapy. In many cases, such as with the implantation of so-called "bionic arms" and "legs", where neuro-pathways have been utterly destroyed, this regimen may last many weeks or months as the brain, which already "knows" where it wants the hand or foot to go must relearn how to get that message across to the hand or foot.
With Introculus's hemi-ocular salvage technique, much of the retraining regimen required by the older "whole eye" bionic replacement process, is made moot. Because the retina and optic nerve remain intact and active, the training regimen immediately proceeds on to the final stages: device calibration, facial muscle to device movement exercise and most importantly, device-retina training.
This concludes our presentation on the implantation procedure for the Introculus ITVS Device. Thank you for considering Introculus for all your CyberForce's vision needs!
