Summary: By evaluating the features of anterior segment optical coherence tomography (AS-OCT), it was found that posterior stromal ripples and detachment axial extension are the main risk factors for graft detachment worsening in Descemet's membrane endothelial keratoplasty (DMEK). Patients showing these features should be closely monitored to identify the need for re-bubbling at an early stage, thus improving surgical outcomes.

Summary: This retrospective study analyzed the outcomes and risk factors of failure in Descemet's membrane endothelial keratoplasty (DMEK) for graft failure after penetrating keratoplasty (PKP). The study found that DMEK is a feasible option with fast visual recovery and low risk of complications in patients with graft failure after PKP. However, larger studies are needed to analyze intraoperative and donor-related factors.

Summary: This study compared the central corneal thickness before and after DSAEK and DMEK surgeries, and evaluated the recipient corneal thickness following DSAEK. The results showed that there was no significant difference in central corneal thickness between DSAEK and DMEK eyes before surgery, but the central corneal thickness was slightly greater in DSAEK eyes compared to DMEK eyes at 6 months post-surgery. However, there was no significant difference in recipient corneal thickness following DSAEK and central corneal thickness following DMEK at 6 months.

Summary: The study aimed to determine the primary axis of Descemet's membrane scrolling and investigate the impact of oval trephination along the axis of least scrolling. Results showed that Descemet's membrane primarily scrolled along the horizontal axis, and vertically oval samples displayed minimal scrolling. Additionally, the degree of scrolling was not influenced by the distribution of elastin.

Summary: The paper reports a rare case of retaining the Descemet's membrane (DM) after penetrating keratoplasty (PKP). The investigation was conducted to explore etiologies, expected sequelae, and outcome of neodymium-doped yttrium aluminum garnet (Nd:YAG) laser membranectomy. It is concluded that retention of DM following PKP is a rare but possible complication, and high index of suspicion is required for proper diagnosis and management.

Summary: The study included five males and two females aged 54-82 years with corneal oedema due to Pseudophakic bullous keratopathy (n=5), Fuchs' endothelial dystrophy (n=2). In all cases, the technique allowed proper determination of the graft's orientation.

Summary: This study compares the blebs generated by PRESERFLO and trabeculectomy procedures, and finds nuanced morphological differences between the two. PRESERFLO blebs exhibit fewer conjunctival cysts and cavernous changes, but overall bleb dimensions are similar. Understanding these distinctions is vital for clinicians to make informed postoperative decisions and avoid misinterpretation of bleb morphology.

Summary: This study reported the utility of preoperative anterior segment optical coherence tomography (ASOCT) in decision-making for stripping of the Descemet membrane (DM) during Descemet membrane endothelial keratoplasty (DMEK) in eyes with congenital hereditary endothelial dystrophy (CHED). The outcomes of non-DM stripping DMEK were similar to standard DMEK in this small series.

Summary: This study evaluated the outcomes of tuck-in DALK for managing corneal ectasia after RK. The results showed that this method could successfully improve visual acuity and restore corneal thickness with minimal risk of complications.

Summary: This study compared the outcomes of deep anterior lamellar keratoplasty (DALK) and penetrating keratoplasty (PK) in keratoconic eyes with or without previous hydrops. The results showed that visual outcome, astigmatism, and maximum keratometry (K-max) were similar between eyes with and without previous hydrops, regardless of the surgical method. However, eyes with previous hydrops had a higher risk of complications.

Summary: This study retrospectively analyzed 18 eyes with complicated Descemet's membrane detachment (DMD) and reported clinical outcomes after surgical intervention. The results showed that in eyes with previous penetrating keratoplasty (PKP), AS-OCT demonstrated rupture of Descemet's membrane (DM) in some cases, but spontaneous reattachment occurred in most cases within 8 weeks. Visual acuity significantly improved after surgical treatments such as PKP. In conclusion, PKP is an effective treatment option for complicated DMD.

Summary: This study compared the efficacy and safety of femtosecond laser-assisted deep anterior lamellar keratoplasty (F-DALK) with manual-trephination DALK (M-DALK) in treating keratoconus. The results showed that F-DALK provided better early visual acuity and reduced the intraoperative perforation rate compared to M-DALK. Both techniques were found to be comparable in terms of refractive outcomes and other complications.

Summary: Optical PK within a previous TLK is a safe and efficient technique for treating deep corneal opacity associated with extensive vascularization and peripheral thinning. Extended follow-up period is necessary to assess endothelial cell loss and long-term efficacy of the procedure.

Summary: The purpose of this study was to report the demographic and clinical characteristics of US patients with keratoconus undergoing DALK or PK, as well as the complication rates for the two procedures. A retrospective review of health records was conducted and the results showed that the complication rates for DALK and PK were low at 1 year and beyond.
