“…Another method is to create a site of temporary RD at the posterior pole and a retinotomy near the inferotemporal vessels, followed by fluid-air exchange. After these procedures, the patient is asked to maintain an upright position for a short period post-operatively to allow displacement of the PFCL droplets ( 13 ). However, PFCL displacement will not eliminate the long-term risk of reverse migration of the PFCL to the macular foveal center, potential retinal toxicity or extramacular retinal hole formation.…”

“…Our results demonstrate that early surgical intervention for subfoveal PFCL retention is beneficial. The ultimate visual prognosis may be affected by the location, size, and duration of subfoveal PFCL retention ( 3 , 13 ). It is important to mention that three of our patients underwent phacoemulsification and intraocular lens (IOL) implantation at the same time as subfoveal PFCL removal, and two patients underwent IOL implantation after this operation.…”

IntroductionTo report a novel combining a 25-gauge retrobulbar needle with a built-in 30-gauge needle surgical technique for subfoveal perfluorocarbon liquid (PFCL) removal.Materials and MethodsFourteen eyes of 14 patients who underwent subfoveal PFCL removal with a 25-gauge retrobulbar needle combined with a built-in 30-gauge needle were studied. The 30-gauge needle was inserted into the 25-gauge retrobulbar needle. The bent tip of the built-in 30-gauge needle was used to create a 30-gauge retinotomy at the farthest edge of the subfoveal PFCL droplet. Then, a flute cannula was used to aspirate the PFCL through the previously created retinotomy. The best-corrected visual acuity (BCVA) was determined, previous surgical history and post-operative complications were recorded.ResultsFourteen cases were analyzed. Most eyes (92.85%) showed an improvement in BCVA after surgery. The mean change in the BCVA was −0.7 ± 0.72 logarithm of the minimum angle of resolution (logMAR) units (p = 0.006). Post-operative complications included a self-healing macular hole in one eye and vitreous hemorrhage in one eye. Post-operative optical coherence tomography confirmed removal of the subfoveal PFCL with restoration of the macular fovea.ConclusionCombining a 25-gauge retrobulbar needle with a built-in 30-gauge needle to remove subfoveal PFCL is easy to perform and carries little potential risk of subretinal impairment. This method also provides relatively good macular contour with functional improvement.

“…It is difficult to remove all residual PFCL globules from the vitreous. Subretinal PFCL is more difficult to remove 13 , 14 . Therefore, the kebab technique has the advantage of allowing phacoemulsification without PFCL in the anterior chamber.…”

We developed a new method to retrieve a dropped nucleus of the lens via a small incision using bipolar pencils, the kebab technique, to solve the lack of small-gauge fragmatomes, and the expense and toxicity of perfluorocarbon liquids (PFCL). A total of 8 eyes in 6 patients underwent this technique and were reviewed. After vitrectomy, the dropped nucleus of the lens was lifted from the retina by adhesion with a bipolar pencil, and phacoemulsification was performed while rotating the lens. The outcome measures were best-corrected visual acuity (BCVA), intraocular pressure (IOP), and corneal endothelial cell density before and after surgery. Surgical indications included zonular weakness, trauma, acute angle closure attack, and phacolytic glaucoma. At 1 month, BCVA improved from a mean (standard deviation, SD) 1.67 logMAR (0.90) to 1.14 logMAR (1.01). The mean preoperative IOP was 24.5 (16.8) mmHg and postoperative IOP was 11.0 (2.8) mmHg. The mean preoperative corneal endothelial cell count was 2600 (322) cells/mm2 (one eye was unmeasurable) and postoperative corneal endothelial cell count was 2387 (431) cells/mm2. There were no postoperative complications. The retrieval of a dropped nucleus of the lens using a bipolar pencil enables small incisions without using PFCL.
