The utility model relates to an autoclave with heat insulation barrier layer which is used for the growth of artificial lens through the hydro-thermal method. The autoclave with heat insulation barrier layer is composed of an autoclave whose reaction chamber is phi 42-60*760-1100mm and a heat insulation barrier layer which is arranged on the corresponding position of the autoclave body of the autoclave. The heat insulation barrier layer comprises an upper and a lower heat insulation rings and a heat insulation layer. The utility model has a good effect of heat insulation and warming, and the temperature difference and the stability of the crystal region and the dissolving region in the reaction chamber can be ensured; the utility model is favourable for the growth of the artificial lens of good quality, high speed, and stabilization; besides, the utility model has the advantages of convenient operation and maintenance.
