Abstract
PURPOSE To provide insights into morphologic and functional features of eyes with complicated Descemet's membrane detachment (DMD) and report clinical outcomes after surgical intervention. METHODS Retrospective study of 18 eyes with complicated DMD between 2010 and 2022. Complicated DMD was defined if any of the following criteria applied: prior penetrating keratoplasty (PKP), corneal thinning, total DMD or persistent DMD after Air/Gas-Descemetopexy. Causes, surgical management, and clinical outcomes were analyzed. Scheimpflug tomography, anterior segment optical coherence tomography (AS-OCT) and histologic examination were performed to characterize corneas with DMD. RESULTS Fourteen eyes with prior PKP developed spontaneous DMD after 24.2 ± 12.9 years (range = 18 months - 47 years, median = 25.7 years). Complicated DMD without prior PKP was associated in three eyes after cataract surgery and in one eye after infectious keratitis. In cases with previous PKP, AS-OCT demonstrated rupture of Descemet's membrane (DM) in five eyes and spontaneous reattachment was found in four eyes within 8 weeks of initial diagnosis, with no rupture of DM in any of the cases. There was no rupture of DM in corneas without previous PKP. After prior keratoplasty, definitive surgical treatment was repeat PKP in 13 eyes and Air/Gas-Descemetopexy in one eye. In corneas without prior keratoplasty, three eyes underwent PKP and one eye Air/Gas-Descemetopexy. Histological examination of two corneal explants revealed a severely thinned graft-host junction and a disrupted DM close to the graft-host junction. Visual acuity improved from 1.80 ± 0.58 logMAR to 0.75 ± 0.69 logMAR after prior PKP and from 1.45 ± 0.65 logMAR to 0.85 ± 1.13 logMAR without prior PKP. The postoperative course was uneventful in 16 of 18 eyes. CONCLUSION PKP is an effective treatment option for complicated DMD, especially in ectatic corneas, whereas Air/Gas-Descemetopexy or Descemet Membrane Endothelial Keratoplasty do not address the primary issue of the curvature anomaly.

Abstract
A female patient in her 60s presented with an 8-month history of decreased vision in her right eye. She was diagnosed with pseudophakic bullous keratopathy (PBK), and Descemet stripping automated endothelial keratoplasty (DSAEK) surgery was planned. Intraoperative Descemet membrane detachment (DMD) occurred while inserting the lenticule using the Sheets glide technique. The detachment of the Descemet membrane was detected immediately, and air descemetopexy was performed intraoperatively. Postoperatively, the donor lenticule was attached properly to the stromal bed, except for a focal DMD approximately 3 mm in the inferior part of the lenticule. A second descemetopexy was performed 5 days later, resulting in a complete attachment. A DMD in DSAEK lenticule is an extremely rare complication. Early detection and timely intervention with descemetopexy helped achieve a good anatomical and functional outcome.

Abstract
A woman in her 60s was referred to us for management of poor vision following cataract surgery in the right eye. She had undergone manual small incision cataract surgery 12 weeks earlier. Slit-lamp biomicroscopy revealed corneal oedema, a horizontal line at the upper border and the adhered inferior border of detached Descemet's membrane (DM). Clinical diagnosis of impacted Descemet's membrane detachment (DMD) was considered.Surgical intervention with manual schisis and intracameral injection of air was planned. Using the 'push technique,' we tried to place the tip of the 27 gauge cannula between the back of the cornea and detached DM. The tip of the 27 gauge cannula was behind the impacted DM, and air injection was unsuccessful. Using the back-up the 'pull technique,' bent tip of the 27 gauge cannula was used to pull the impacted DMD. This manoeuvre, disimpacted the inferior border and the air bubble, was injected using the 27 gauge cannula. The air bubble unfolded and reattached the DM successfully.

Abstract
RATIONALE The Descemet layer is a dense layer of tissue that does not detach under normal circumstances. Descemet layer detachment may occur after intraocular surgery, but the Descemet layer spontaneously detached after trauma in this child, which is relatively rare. After looking for the cause, we found that the child was diagnosed with congenital glaucoma, and the trauma induced the Descemet's membrane detachment. PATIENT CONCERNS The parents of the patient expected the child to recover the normal shape of the cornea as soon as possible, improve vision, and solve the problem of congenital glaucoma. DIAGNOSES The patient was diagnosed with Descemet's membrane detachment of the left eye and congenital glaucoma in both eyes. INTERVENTIONS During operation, inflation gas is injected into the anterior chamber, the Descemet's membrane is reset, and glaucoma surgery is performed. OUTCOMES The Descemet's membrane in the child's eye was reset, and after glaucoma surgery, the intraocular pressure of the child was normal. LESSONS The analysis of the disease is not only to solve the problems seen but also to deeply analyze the internal causes and pathological changes in combination with the symptoms and signs, so as to discover the essence of the problem and solve the fundamental problem of the patient.

Abstract
A 62-year-old woman was referred with poor vision following manual small incision cataract surgery. On presentation, the uncorrected distance visual acuity in the involved eye was 3/60, whereas slit-lamp examination revealed a central corneal edema with the peripheral cornea relatively clear. Direct focal examination with a narrow slit upper border and lower margin of detached rolled up Descemet's membrane (DM) could be visualized. We performed a novel surgical approach, "double-bubble pneumo-descemetopexy." The surgical procedure included unrolling of DM with "small air bubble" and descemetopexy with "big bubble." No postoperative complications were observed, and best corrected distance visual acuity improved to 6/9 at 6 weeks. The patient had a clear cornea and maintained BCVA 6/9 during 18 months at follow-up. Double-bubble pneumo-descemetopexy, a more controlled technique, provides a satisfactory anatomical and visual outcome in DMD without the need for endothelial keratoplasty (Descemet's stripping endothelial keratoplasty or DMEK) or penetrating keratoplasty.

Abstract
Our study aims to investigate a simple repair algorithm for Descemet's membrane detachment (DMD) following phacoemulsification with Pentacam and anterior segment optical coherence tomography (AS-OCT). Twelve patients with DMD were included in this retrospective study. All cases had persistent corneal edema after phacoemulsification and no improved response to conservative treatment. The repair algorithm consisted of delineating the DMD with the Pentacam and AS-OCT, paracentesis, and intracameral air bubble performed at the slit lamp, followed by immediate supine position. At one month, the final status of Descemet's membrane (DM), best-corrected visual acuity, and incidence of complications were noted. DMD was involved in the visual axis in all cases. The mean interval between phacoemulsification and repair was 5.3 ± 1.2 days. Complete reattachment of DM and corneal clarity occurred in all 12 eyes. Eleven (91.7%) eyes underwent one repair procedure, while one eye (8.3%) underwent a repeat procedure. No adverse events were found. Minor post-intervention complications included temporary increased intraocular pressure due to pupillary block in one eye (8.3%). In conclusion, our modified and simplified repair algorithm for DMD can be performed safely as an outpatient procedure, with accurate delineation using a Pentacam and AS-OCT. It may provide new insight into the timely diagnosis, evaluation, and management of DMD.

Abstract
PURPOSE Descemet´s membrane ruptures (with a discontinuation of Descemet´s membrane and double detached coiled edges) in the context of complicated anterior segment surgery have rarely been described and its management can be challenging. We report a modified Descemet stripping only (DSO) technique associated with ripasudil drops to treat these cases when other techniques fail. METHODS We describe two cases of large Descemet´s membrane detachments associated with Descemet´s ruptures after cataract surgery that did not respond to two SF6 intracameral injections. As the detached Descemet's membrane and coiled edges might have prevented endothelial cell migration, we decided to perform a modified DSO with post-operative ripasudil drops to promote corneal clearance. RESULTS Both cases improved significantly in unaided and best corrected visual acuity (BCVA), corneal clearance and pachymetry, avoiding the need for an endothelial keratoplasty. Endothelial cells were observed on specular microscopy within the area of the descemetorhexis. CONCLUSION DSO with ripasudil drops might be a valuable tool to recover corneal clearance and avoid endothelial keratoplasty in complex Descemet´s membrane detachments with ruptures that do not respond to other treatments.

Abstract
Importance The conventional 2.2-mm clear corneal incision is relatively narrow compared with the sleeves of Phaco handpieces, resulting in friction at the incision site and increased risk of incision-related Descemet membrane detachment (DMD). The modified 2.2-mm incision only enlarged internal width to 3.0 mm, forming a trapezoid incision shape, which may reduce the friction of surgical instruments and decrease the risk of incisional DMD. Objective To compare the incidence of incision-related DMD between eyes undergoing modified vs conventional 2.2-mm incision phacoemulsification for hard nuclear age-related cataract. Design, Setting, and Participants This double-masked, parallel randomized clinical trial was conducted from July 22, 2019, to January 22, 2020, at Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou, China. The study included patients with age-related cataract and nuclear opalescence grade of 4.0 or greater based on the Lens Opacities Classification System III. Patients were enrolled in this study according to the following inclusion criteria: (1) age between 65 to 90 years; (2) pupil size of 6 mm or greater after dilation; (3) Lens Opacities Classification System III nuclear opalescence grade of 4.0 or more; and (4) corneal endothelial cell density greater than 1500 cells/mm2. Interventions Modified (enlarged internal width to 3.0 mm) or conventional 2.2-mm incision phacoemulsification with intraocular lens implantation. Main Outcomes and Measures Incidence of incision-related DMD at postoperative day 1. Results A total of 130 eyes of 130 patients were randomized into the conventional group (n = 65) or the modified group (n = 65). The mean (SD) age of participants was 74.5 (5.9) years and 74.3 (6.0) years in the conventional and modified groups, respectively. A total of 26 participants in the conventional group (40%) and 27 in the modified group (42%) were men. Compared with eyes in the conventional group, the incidence of DMD in eyes in the modified group was significantly lower at postoperative day 1 (difference, 26.15; 95% CI, 9.60-42.71; P = .003). The difference at postoperative day 7 was 16.92 (95% CI, 2.91-30.94; P = .02). The length of DMD (postoperative day 1: difference, 0.188; 95% CI, 0.075-0.301; P = .002) and maximal corneal thickness at incision site (postoperative day 1: difference, 0.032; 95% CI, 0.006-0.057; P = .02; postoperative day 7: difference, 0.019; 95% CI, 0.003-0.035; P = .02) were lower in the modified group, while visual quality parameter modulation transfer function (postoperative day 1: difference, -0.033; 95% CI, -0.064 to -0.001; P = .04) was higher. No difference was observed between the 2 groups in best-corrected visual acuity, central corneal endothelium loss, or surgically induced astigmatism at any follow-up time. There were no intraoperative complications in the 2 groups. Conclusions and Relevance These findings suggest that modified 2.2-mm trapezoid incision phacoemulsification reduces the incidence of DMD for hard nuclear age-related cataract at postoperative day 1 and might be considered in patients at high risk of incision-related DMD, although the clinical relevance cannot be determined with certainty from this trial. Trial Registration ClinicalTrials.gov identifier: NCT04014699.

Abstract
PURPOSE To describe the clinical characteristics and treatment of spontaneous Descemet membrane (DM) detachment occurring decades after penetrating keratoplasty (PK). METHODS A multicenter interventional case series design was used. We reviewed the medical records of 4 patients with a history of PK presenting with spontaneous DM detachment at 3 university hospitals in Israel and an ocular surgery institute in The Netherlands in 2016 to 2019. Patient demographic and clinical data, postoperative best corrected visual acuity, findings on preoperative and postoperative anterior segment optical coherence tomography (AS-OCT), and graft survival were recorded. RESULTS Patients were aged 46 to 50 years. All had undergone PK for keratoconus 20 to 26 years previously. Patients presented within 18 to 180 days of onset of visual disturbance. Symptoms included sudden painless visual loss (2 patients), gradual visual loss and foreign body sensation (1 patients), and visual loss not otherwise specified (1 patient). Slit-lamp examination showed corneal edema, and AS-OCT showed DM detachment of variable extent. In 2 patients, the initial diagnosis was graft rejection and failure. Treatment consisted of anterior chamber injection of air (n = 3) or 20% SF6 (n = 1). In 3 patients, the DM reattached and the cornea regained its clarity. The fourth patient had persistent DM detachment that required repeated PK. CONCLUSIONS Spontaneous DM detachment can mimic late graft failure in patients after PK. If diagnosed early, DM reattachment may be performed by air/gas injection, avoiding repeated keratoplasty. Eyes with presumed late penetrating graft rejection or failure should be examined by AS-OCT to exclude DM detachment.

A Comparative Study between Air Bubble Tamponade Alone versus Air Bubble Tamponade with Internal Fluid Aspiration for Nonplanar Descemet's Membrane Detachment after Phacoemulsification. J Ophthalmol 2021; 2021:9953418. [PMID: 34327013 PMCID: PMC8277505 DOI: 10.1155/2021/9953418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Revised: 05/21/2021] [Accepted: 06/26/2021] [Indexed: 11/22/2022] Open
Abstract
Purpose To compare the efficacy of air bubble tamponade alone versus air bubble tamponade with internal fluid aspiration for nonplanar Descemet's membrane detachment after clear corneal incision phacoemulsification. Methods This study is a prospective, intervention, comparative randomised clinical trial, conducted at a private eye centre, Ismailia, Egypt, from March 2019 to March 2020. It contained 30 eyes of 24 patients who had postphacoemulsification nonplanar Descemet's membrane detachment involving the periphery and the central area of the cornea (>50% of the cornea) with corneal oedema. The patients were divided into two groups: group A: patients with nonplanar DMD affecting the central cornea treated by air bubble tamponade only and group B: patients with nonplanar DMD affecting the central cornea treated by air bubble tamponade augmented by internal fluid aspiration. Trial Registration: This trial was registered at www.pactr.org and the identification number for the registry is PACTR202006612296119. Results During the 12-month study period, this study included 30 eyes (24 patients) out of 1356 phaco surgeries with postphacoemulsification nonplanar Descemet's membrane detachment. Six patients had DMD in both eyes, eight patients had DMD in the right eye, and ten patients had DMD in the left eye. All patients have successful surgeries without complications. The calculated incidence rate for visually significant DMD was 2.2% per year. The mean ± SD time interval from cataract surgery to the primary intervention was 4.2 ± 1.1 days. Descemet's membrane was attached in 56.25% of patients in group A (9 out of 16 eyes) and 92.6% of patients in group B (13 out of 14 eyes) with a minimum of one-month follow-up. Conclusion Air descemetopexy combined with the internal fluid aspiration demonstrated to be more efficient than air descemetopexy only to treat Descemet's membrane detachment following phacoemulsification. It should be tried before planning other major surgeries in patients with severe Descemet's membrane detachment.

Abstract
PURPOSE To report a case of late spontaneous detachment of Descemet membrane (DM) in a donor penetrating keratoplasty (PKP) graft and its successful management using a supra-Descemetic venting incision combined with gas descemetopexy. METHODS Case report with review of literature. RESULTS A 56-year-old man who had undergone PKP after acute hydrops in pellucid marginal degeneration 27 years before presentation experienced sudden onset vision loss. Clinical features mimicked acute graft rejection but detailed evaluation and anterior segment optical coherence tomography showed a DM detachment (DMD) of the graft. Ten weeks after the onset of DMD, he underwent descemetopexy with a supra-Descemetic stromal venting incision and sulfur hexafluoride gas tamponade. DM reattached with complete resolution of graft edema. CONCLUSIONS Late spontaneous DMD of the graft after PKP is very uncommon and must be differentiated from acute graft rejection. Anterior segment optical coherence tomography may help to diagnose this entity that can be managed successfully despite late intervention. The addition of a venting incision that drains fluid from the supra-Descemetic space can increase the chance of success of descemetopexy when compared with descemetopexy with air or gas alone.

Abstract
Question When and how does incision-related Descemet membrane detachment (DMD) occur during cataract surgery? Findings In this case series of 133 patients with cataract, DMD was found in 125 cataract operations (94.0%) and occurred mostly during the phacoemulsification step (69 cases [55.2%]); DMD also increased throughout surgery. Meaning These findings suggest that incision-related DMD mainly occurs during the surgical steps in which the instruments create the greatest friction at the incision site and that severity is associated with the level of ultrasonic energy and length of time of phacoemulsification. Importance Incision-related Descemet membrane detachment (DMD) is a common complication of cataract surgery. Most postoperative severe DMD that leads to corneal decompensation originates from intraoperative incision-related DMD. It is important to determine the incidence, extent, and associated risk factors of intraoperative DMD at each step of surgery to help in formulating precise and effective prevention strategies. Objectives To investigate the intraoperative development of incision-site DMD associated with a 2.2-mm clear corneal incision during cataract surgery and to analyze its associated factors. Design, Setting, and Participants In this case series, consecutive, prospectively enrolled 133 patients with cataract 50 to 90 years of age (133 eyes) undergoing coaxial 2.2-mm clear corneal microincision phacoemulsification with intraocular lens (IOL) implantation between January 1 and March 31, 2019, at Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou, China, were studied. Exposures Coaxial 2.2-mm clear corneal microincision phacoemulsification with IOL implantation. Main Outcomes and Measures Real-time incidence and extent of intraoperative incision-related DMD at each step of surgery. Results Among 133 patients with cataracts (mean [SD] age, 72.3 [8.1] years; 77 [57.9%] female), DMD was encountered in 125 eyes (94.0%), occurring at the following steps: capsulorrhexis (2 [1.6%]), hydrodissection (7 [5.6%]), phacoemulsification (69 [55.2%]), irrigation-aspiration (44 [35.2%]), and IOL implantation (3 [2.4%]). The extent of DMD increased during the operation (mean [SD] difference between final and initial relative DMD length, 22.8% [1.4%]; 95% CI, 20.0-25.6; P < .001). Associations for the extent of DMD found in multivariate stepwise analyses included time of ultrasonography (β = 0.34; 95% CI, 0.17-0.50; P < .001), equivalent mean ultrasonic power (β = 87.8; 95% CI, 19.1-156.4; P = .01), and the presence of DMD at the anterior and posterior wound margins (coefficient = 16.7; 95% CI, 6.4-26.9; P = .002). Conclusions and Relevance The results of this case series suggest that friction of surgical instruments has the greatest association with incisional DMD. Decreasing ultrasonic energy and phacoemulsification time may reduce the severity of incisional DMD.

Abstract
Descemet’s membrane detachment (DMD) is a complication fundamentally associated with cataract surgery, the subclinical presentation being higher than expected. There are many varied treatments, from simple observation to penetrating keratoplasty. We present a case report of a 78-year-old male patient, without comorbidities, who underwent cataract surgery with phacoemulsification plus intraocular lens implantation in the capsular bag of the left eye. During the intraoperative procedure, he presented a DMD (height of 350 um and length of 3 mm in Zone 1 according to the HELP algorithm), managed with adaptive viscoelastic under the soft-shell technique in the same operative act, injection of iso-expansile SF6 (20%) intracameral plus postural positioning for 2 hours carried out 48 hours after surgery plus intensive topical treatment with hypertonic sodium chloride and steroidal anti-inflammatory drugs. At 72 hours after the operation of the application of the gas bubble, he presented with a transparent cornea and a best-corrected visual acuity of 20/80, which finally for his ophthalmological control at 8 weeks presented definitive resolution of the case in the AS-OCT and with a BCVA of 20/30.

Abstract
PURPOSE Descemet's membrane detachment (DMD) is a rare but potentially serious complication of cataract surgery. Although there are no consensual guidelines regarding the diagnosis or treatment of DMD, incorrect treatment may result in irreversible corneal changes with visual sequellae. The purpose of our study is to describe the diagnosis and treatment of DMD. METHODS We report a series of 9 cases of DMD, their diagnosis, treatment and outcomes. We tested the HELP protocol retrospectively against our 9 real-life cases. RESULTS Two cases recovered with simple medical management, 4 required air-bubble descemetopexy, and three required keratoplasty. Our study revealed that the main factor associated with poor outcomes is late diagnosis and management. CONCLUSION Our series illustrates the importance of proactive management and timely diagnosis by performing anterior segment OCT in the setting of persistent postoperative corneal edema.

Abstract
PURPOSE To study the outcomes of Descemet membrane (DM) suturing for moderate to severe Descemet membrane detachment (DMD) after cataract surgery. METHODS This is a retrospective case review of all patients who underwent DM suturing for moderate to severe DMD after cataract surgery in a tertiary training eye care hospital from January 2017 to December 2017. Demographic details, type of cataract, type of cataract surgery, intraoperative complications, severity of DMD, time to repair, and post-DM suturing visual and clinical outcomes were documented. RESULTS Forty-nine patients were included during the study period with a mean age of 67.7 ± 9.7 years. In total, 79.5% had immature cataracts. Median precataract LogMAR visual acuity was 0.78 (IQR 0.69-1.13). In total, 61.2% underwent manual small-incision cataract surgery, 32.6% had phacoemulsification, 2% had extracapsular cataract extraction (ECCE), and 6% underwent small-incision cataract surgery with trabeculectomy. In total, 44.9% were operated on by trainees and 55.1% were operated on by consultants. In total, 22.4% had primary air descemetopexy during the cataract surgery and failed treatment. All patients had attached DM in the immediate postoperative period. None of them had secondary angle closure glaucoma. At the final follow-up, 42 (85.7%) had clear corneas and 7 (14.3%) had corneal decompensation needing endothelial keratoplasty. Of these 7 patients, 2 (28.5%) had Fuchs dystrophy and 3 (42.8%) had associated DM loss. The median LogMAR visual acuity at the final follow-up was 0.39 (IQR 0.3-0.78). CONCLUSIONS DM suturing can reattach DM, especially in moderate to severe, recurrent DMD with fewer postoperative complications and thereby reduce the need for corneal transplantation.

Management of Descemet’s Membrane Detachment after Cataract Surgery—A Case Series. REPORTS 2020.

Abstract
Descemet’s membrane detachment (DMD) is an uncommon, vision-threatening, ocular surface complication of cataract surgery. Among several treatment strategies, sulfur hexafluoride (SF6) descemetopexy is the standard of care. Herein, we report three cases of DMD after cataract surgery managed with SF6 descemetopexy, showing different outcomes. Anatomical success was achieved in cases 1 and 2 while intraocular pressure (IOP) was elevated in case 2. In case 3, despite SF6 descemetopexy, recurrent DMD was observed. Due to persistent corneal edema and possible corneal decompensation in case 3, Descemet’s stripping automated endothelial keratoplasty was performed and a clear graft was found at the final visit. In conclusion, descemetopexy with 20 % SF6 is an effective and safe procedure for repairing DMD in most cases. Pupillary block with elevated IOP is another concern and prophylactic peripheral iridectomy is recommended. For recurrent DMDs, repeat descemetopexy could be considered. However, close monitoring is advocated since secondary management, such as endothelial keratoplasty, may be required.

Abstract
Descemet membrane detachment (DMD) is a potential vision-threatening complication that occurs most commonly after cataract surgery. DMD has also been reported to occur in various other surgeries such as keratoplasty, iridectomy, vitrectomy, trabeculectomy, holmium laser sclerostomy, alkali burn, and viscocanalostomy. Major risk factors include advanced age, preexisting endothelial diseases like Fuchs dystrophy or abnormality in the Descemet membrane and stromal interface, hard cataract, prolonged surgical time, ragged clear corneal incisions, and inadvertent trauma with blunt instruments or phacoemulsification probe. Most DMDs are peripheral and resolve spontaneously. Large, central DMDs if not managed appropriately may lead to corneal decompensation and opacification. Several authors have classified DMD depending on its configuration, height, extent, length, and position with respect to pupil. Anterior segment optical coherence tomography has been used to confirm and classify DMD and can also aid in deciding the management plan. Spontaneous reattachment of the DM with conservative management may occur in cases with small, peripheral, planar DMD with nonscrolled edges. Cases with nonplanar, central DMD, scrolled edges, and length >2 mm, however, have to be managed surgically. Descemetopexy is the gold standard for the management of DMD. Other management options include mechanical tamponade, suture fixation, descemetotomy, interface drainage, and keratoplasty. Prompt diagnosis and timely management often leads to a good visual outcome.

Abstract
Purpose: To present a case with the late-onset post-phacoemulsification Descemet’s membrane detachment that has been treated successfully. Methods: Case report. Results: A 68-year-old female patient presented with the complaint of decreased vision in her pseudophakic left eye after a 4-week silent post-phacoemulsification period. In the biomicroscopy, corneal oedema was seen to be prominent on the nasal incision side. Anterior segment optical coherence tomography objectively revealed the presence of Descemet’s membrane detachment. Treatment of descemetopexy was applied by injecting 0.3-mL perfluoropropane gas into the anterior chamber. No complication associated with descemetopexy was noticed during recovery. Total Descemet’s membrane detachment reattachment was achieved and perfluoropropane gas resorption from the anterior chamber was completed by the end of 1-month post-injection. The cornea was transparent and best corrected visual acuity increased to 20/20. Discussion: DMD is a rare complication following phacoemulsification and this patient had not any preoperative, intraoperative, or postoperative risk factors for DMD.It generally occurs in early-postoperative period and late-onset DMDs have been reported less frequently.The success rates with intracameral gas injections in similar cases have been reported to be 90% - 95%. Conclusion: To the best of our knowledge, this is one of the latest onset post-phacoemulsification Descemet’s membrane detachment cases in literature that has been treated successfully. The results of this case showed that descemetopexy is a safe and effective treatment method for late-onset post-phacoemulsification DMD.
