ABSTRACT
@#AIM: To investigate the clinical effects of soft corneal contact lens after excision of pterygium and limbal stem cell transplantation in elderly patients. <p>METHODS:Totally 90 patients(90 eyes)with unilateral pterygium were divided into two groups according to the random number table method. The observation group(45 cases)were treated with soft corneal contact lens after corneal limbal autograft transplantation merely, 45 cases of the control group were treated by autologous limbal stem cell transplantation. According to the data obtained from two groups of patients, the following indicators were compared: corneal healing time, symptom score of corneal irritation in 1d, 3d, 5d, 7d after operation, postoperative 24h、48h, two groups of patients with pain(VAS score),the recurrence rate of pterygium. <p>RESULTS: In control group, the corneal healing time(5.38±1.67d)was more than that of observation group(3.10±1.12d; <i>P</i><0.05); Score of the corneal stimulation symptom and VAS after operation were higher than those of the control group(<i>P</i><0.05), and the difference in recurrence of pterygium was not statistically significant(<i>P</i>>0.05).<p>CONCLUSION: Autologous corneal stem cells combined with soft corneal contact lens in treatment of elderly patients with pterygium can reduce the healing time, and reduce the postoperative symptom of corneal irritation, meanwhile it has no effect on the recurrence rate of pterygium.
ABSTRACT
AIM: To investigate the effect of rigid contact lens in the treatment after pterygium excision and limbal stem cell transplantation in senile patients.METHODS: Totally 90 elderly patients diagnosed as unilateral pterygium in our hospital from March 2015 to March 2016 were selected and divided into two groups, observation group and control group, 45 case with 45 eyes in each group.Observation group was treated with limbal stem cell transplantation and rigid contact lens.Control group was treated with limbal stem cell transplantation only.The following indicators were observed and compared: corneal healing time, visual analogue score(VAS) at 1, 3, 5 and 7d after surgery and the recurrence rate of pterygium.RESULTS: The score on corneal irritation of observation group was significantly lower than that of control group (P0.05).CONCLUSION: Autologous corneal stem cell transplantation combined with rigid contact lens for pterygium in elderly patients is effective with shorter healing time and less pain, and it does not increase the recurrence rate.
