A case of corneal burn caused by arc light due to electrical short is reported. Specialist examination: ischemic areas of the temporal limbus bulbar conjunctiva in both eyes were less than 1/3, the corneal epithelium was white and cloudy, and the epithelium was partially peeled. The corneas became transparent after 2 weeks’ treatment of removing the white necrotic tissue, anti-inflammatory and dilating pupil. During the follow-up within 3 months, the patient’s lens and fundus showed no obvious abnormalities. The injury mechanism of arc light caused by electrical short to the eyeball is discussed.
随着白内障手术由复明性向屈光性转变,对角膜的散光矫正显得越来越重要。而角膜散光不仅仅应该关注角膜前表面的散光数据,更应该考虑角膜后表面的散光,否则对散光人工晶状体植入矫正角膜散光可能出现不同程度的术后屈光误差。角膜后表面散光均值约为0.37 D,且多数情况下会产生逆规散光的效果,因此在进行散光型人工晶状体计算时应考虑到这一特点,进一步防止术后欠矫或过矫的发生。
With the cataract surgery evolving from visual restoration surgery to refractive surgery, surgical correction of corneal astigmatism becomes more and more important. For Toric intraocular lens implantation, the surgeon should not only pay attention to the values in surface of anterior corneal astigmatism but also that in posterior corneal astigmatism. Otherwise,unwanted postoperative refractive errors may occur. The mean value of posterior corneal astigmatism was around 0.37 D.In most cases, the posterior corneal astigmatism produces against-the-rule effect. Therefore, the above-mentioned feature of posterior corneal astigmatism should be noticed to prevent the under-correction or over-correction effect of toric lens.
目前对于成人圆锥角膜(keratoconus,KC)的研究已经很广泛,而对于儿童KC的研究则较少,其诊断和治疗常常基于成人KC的研究基础。与成人KC相比,儿童KC的发展更迅速、造成的后果更严重,其导致的儿童视觉障碍会追随其一生,对其生活质量以及教育发展产生严重的负面影响。为了对儿童KC的治疗有较全面的认识和理解,本文针对近几年儿童KC的治疗进展,对不同治疗方法的安全性、有效性和治疗时机等方面进行综述。
At present, the research on adult keratoconus has been extensive, while the research on pediatric keratoconus is few. The diagnosis and treatment of pediatric keratoconus are often based on the study of keratoconus in adults. Pediatric keratoconus is more aggressive than adult keratoconus, resulting in visual impairment that can follow throughout their lives and have a serious negative impact on their quality of life and educational development. In this paper, according to the treatment progress of pediatric keratoconus in recent years, the safety, effectiveness, and treatment timing of different treatment methods were summarized, in order to have a more comprehensive understanding of the treatment of pediatric keratoconus.

Objective: Due to the limitations of small imaging field of view of in vivo confocal microscopy (IVCM) or the incapability of cellular imaging of traditional optical coherence tomography (OCT) in human corneal imaging, this study was designed to develop a novel high-resolution in vivo human corneal imaging system based on full-field OCT (FFOCT). Methods: The FFOCT system utilized a high numerical aperture air immersion microscope objective and a high-speed area array CMOS camera with two-phase modulation image processing algorithm to achieve high-speed high-resolution non-contact imaging of human cornea. To verify its feasibility, in vivo cornea imaging at different depth was performed on a healthy human subject. Results: The FFOCT system achieved a theoretical lateral imaging resolution of 1.7 μm, an imaging field of view of 1.26 mm×1.26 mm, and an imaging rate of 275 Hz/s. High-resolution FFOCT images of the main structural layers of cornea were achieved by imaging a healthy human cornea in vivo with this system in a non-contact way. Conclusion: The FFOCT human corneal imaging system combines the advantages of the non-contractness and the large imaging field of view of traditional OCT with the cellular lateral resolution of IVCM, potentially providing a new imaging system for the research and clinical diagnosis and treatment of corneal diseases.
