Purpose:To evaluate objectively the clinical efficacy and safety of recombinant human epidermal growth factor(rhEGF)on enhancing corneal epithelial defect healing.Methods:A prospective,random study was carried out.The 153 corneal blindness cases (153 eyes)with limbal normality were treated by penetrating keratoplasty in which each graft measured 7 5mm in diameter and all donor epithelia were removed during operation.All the 153 cases were randomly divided into ecperimental groups(91 eyes)treated by rhEGF eyedyops,positive control group (31 cases)treated by Solcoseryl Eye Gel,and negative group (31 cases)treated by vehicle.The healing rates of corneal epithelium were observed postoperation.Results:Time until epithelium defect healing was significantly shorter with rhEGF compared with vehicle group (P<0 01)and Solcoseryl Eye Gel group (P<0 01).Conclusion:The results indicated that rhEGF improved effectively the healing of corneal epithelial defect.The clinical optimal safety concenration is 20μg/ml.

Objective To evaluate the corneal topography and pachymetry on normal eyes. Methods The Orbscan corneal topography system was used to investigate corneal topography and pachymetry on 46 normal subjects. Results In normal eyes, island shape was the most common type in the elevation topography of anterior corneal surface, followed by incomplete ridge, regular ridge, irregular ridge and unclassified type. For the elevation topography of posterior corneal surface, the most common type was also the island shape,...

Objective To evaluate the corneal topography and pachymetry on normal eyes. Methods The Orbscan corneal topography system was used to investigate corneal topography and pachymetry on 46 normal subjects. Results In normal eyes, island shape was the most common type in the elevation topography of anterior corneal surface, followed by incomplete ridge, regular ridge, irregular ridge and unclassified type. For the elevation topography of posterior corneal surface, the most common type was also the island shape, followed by regular ridge, incomplete ridge and irregular ridge. The thinnest point of cornea in normal eyes was located (0 90±0 51) mm away from the visual axis with the thickness of (0 55±0 33) mm, which was commonly seen at the inferotemporal quarter of cornea, followed by superotemporal, inferonasal and superonasal quarter. The mean corneal thickness was the least in corneal center and greatest in superior part of cornea. For the color coded map of corneal thickness, oval shape was the commonest type, followed by round shape, eccentric oval shape and eccentric round shape. Conclusions The normal parameters on pan corneal thickness and corneal shape of both anterior and posterior surface will provide much more useful informations in finding abnormal cornea. Orbscan topography system is a useful instrument for the evaluation of corneal shape and thickness, which is helpful in corneal refractive surgeries.

ResultsThe most common type was island shape in the elevation topography of posterior corneal surface. Every group has its own characteristics. The protrusion pole of posterior surface was mostly in inferotemporal, followed by inferonasal, superotemporal and superonasal. There was no significant correlation among diopter and protrusive pole number, the distance of protrusive pole away from visual axis, square of protrusion, the different number of maximum and minimum of protrusion pole( P >0 05).There was significant positive correlation among protrusion pole number, distance of protrusive pole away from visual axis, the square of protrusion, the different values of maximum and minimum of protrusive pole( P <0 05).ConclusionSome parameters referred above are the well indicators for evaluating corneal surface.Orbscan Ⅱcorneal topography system is a useful instrument for the evaluation of corneal appearance in corneal refractive surgeries.
