Visual Results

One of the leading causes of blindness is corneal disorder. By keratoplasty we can restore vision of those patients to some extent and many surgeons are performing keratoplasty on vascularised cornea. Present study was done to evaluate its outcome. Patients (5-70 yrs) were recruited from eye ward of Dhaka Medical College Hospital from January, 2007 to December, 2007. Patients were selected on some criteria. Total 33 cases were evaluated before and after operation. This study was carried out to know pattern of blindness and to obtain the causes of corneal vascularisation and results of keratoplasty on these patients. Among 2 types of grafting all our patients were undergone penetrating keratoplasty. Male predominance (57.50) was marked as male are more prone to corneal diseases and trauma. Considering age group nobody is immune from corneal disease but children and young persons are more vulnerable. Socio-economic status of our maximum patients are middle-class or poor class. We got a rough idea about the causes leading to vascularisation of cornea. Amongst them; trauma, corneal ulcer, chemical injury and under nutrition are noted in our study. Out of 33 healthy grafts, visual improvement occurred in 24 cases. Visual results of grafting on vascularised corneas are variable. Our study concludes that trauma and corneal ulcer are the leading causes of corneal opacity which need penetrating keratoplasty. Whatever the cause of corneal vascularisation, prognosis of keratoplasty on such cases is not disappointing. Rather keratoplasty done on early notified corneal opacity with superficial vascularisation gives satisfactory results.Medicine Today 2017 Vol.29(1): 23-25

Tool materials used in ultramicrotomy are glass, developed by Latta and Hartmann (1) and diamond, introduced by Fernandez-Moran (2). While diamonds produce more good sections per knife edge than glass, they are expensive; require careful mounting and handling; and are time consuming to clean before and after usage, purchase from vendors (3-6 months waiting time), and regrind. Glass offers an easily accessible, inexpensive material ($0.04 per knife) with very high compressive strength (3) that can be employed in microtomy of metals (4) as well as biological materials. When the orthogonal machining process is being studied, glass offers additional advantages. Sections of metal or plastic can be dried down on the rake face, coated with Au-Pd, and examined directly in the SEM with no additional handling (5). Figure 1 shows aluminum chips microtomed with a 75° glass knife at a cutting speed of 1 mm/sec with a depth of cut of 1000 Å lying on the rake face of the knife.
