Experimental observation of living cells on the surface of intraocular lenses / 吉林大学学报(医学版)

ABSTRACT

Objective:To observe the living cells on the surface of intraocular lenses and to compare the cellular numbers and morphology of prestaining to that of poststaining.Methods:Twenty adult pigment rabbit eyes were given posterior chamber intraocular lens implantation.Lenses were extracted and put into 1640 cell cultural liquid immediately on the 1 st,3 rd,7 th,14 th and 28 th day respectively after operatrion.The samples were observed under inverted phase contrast microscope subsequently.Results:We found cells deposited on the surface of lenses from 1 st to 28 th day after operation.These cells contracted and lost three-demensional appearance while its number was less than that of prestaining obviously.Conclusion:A part of cells remove from the surface of lenses during staining;however,we could count the number but could not affirm cellular types which would make error in cellular classification and counting.The fact suggests that we should discover new accurate and reliable methods to avoid mistakes during experiment.
