“…A particular technical difficulty lies in the initiation of the ILM peel and the visualization of the border or edge of the membrane once ILM peeling has been started [21]. It can be difficult to continue an ILM peel if the edge is lost and to determine the total extent of the peel [22,23]. Difficult visualization of the ILM and firm attachment of the ILM to the underlying retina can, thus, present technical challenges even for experienced vitreoretinal surgeons.…”

Intraoperative visualization of the internal limiting membrane (ILM), the choice of a point of vantage for lifting an initial flap, the precision with which the ILM is grasped, adhesion between the forceps and the ILM, thickness, stiffness and elasticity of the ILM as well as monitoring of the completeness of ILM removal are all important factors for safety and efficacy of a chromovitrectomy intervention. The understanding of the underlying physical features of the ILM, such as contrast behavior and bioanatomical and biomechanical properties represent, thus, useful prerequisites for successful macular surgery. New analytical tools, such as atomic force microscopy and chromaticity analysis, allow new insights into ILM material characteristics, permitting a systematic approach to refinement of surgical technique.

“…Peeling of the internal limiting membrane (ILM) for treatment of macular hole is established,1 2 whereas peeling of ILM in macular pucker surgery remains more controversial 3 4. Theoretically, the advantages for ILM peel for macular pucker would include a more complete removal of the epiretinal membrane (ERM).…”

“…2 In both cases the RD leads to vitreous floaters. 3 All these diseases can benefit from pars plana vitrectomy (PPV), the conventional surgical treatment, 4 in which three instruments are brought into the posterior eye under visual control using a surgical microscope. Instead of using invasive instruments, which can result in cataract, 5 less invasive laser systems can be applied to segment EPMs or treat symptomatic vitreous floaters 6,7 without mechanically opening the eye.…”

Surgery with fs-laser in the posterior part of the eye could be useful for separation of tractional epiretinal membrane and vitreous floaters treatment. However, focus degradation occurs near the retina due to induced aberrations by cornea and lens. To overcome this issue, adaptive optics with wavefront sensor and wavefront modulator can be utilized. We demonstrate an alternative concept for image guided femto second laser (fs-laser) surgery in the posterior eye with wavefront sensorless adaptive optics (WFSLAO). Our laboratory setup consists of an 800 nm fs-laser and a superluminescent diode (SLD) with 897.2 nm central wavelength. The SLD is used for optical coherence tomography (OCT) whereby the light for the OCT sample arm and the fs-laser share the same optical path which contains a deformable mirror, scanner and focusing optics. Energy calibrated photodiodes are used to measure the threshold energy for a laser induced optical breakdown inside a water filled chamber that acts as simple eye model. OCT image based metrics were used to determine a set of Zernike polynomials that describe a near optimal deformable mirror state. Such a mirror state improved OCT resolution and at the same time lowered the required fs-laser energy for a laser induced optical breakdown inside the eye model substantially.

Retrospective study of macular holes treated with pars plana vitrectomy

Abstract: Meticulous rapid dissection of adherent, diaphanous 'epiretinal' membrane around the macular hole, combined with gas tamponade and postoperative posturing, result in successful anatomical closure with improved visual acuity.
