Surgical skill of the surgeon can be improved by surgical simulation. Especially in ophthalmology, it is impossible to use real human/non-human primate eyes for ophthalmology surgery practice. However, surgical practice is most important for ophthalmologist. The retina laser surgery is one of the ophthalmology surgeries and it requires more surgical practice for surgeons to use the laser beam precisely to coagulate and fuse small areas of tissue. Dealing with the prospect of vision reduction or vision loss presents a peculiar problem and that can be highly stressful and frustrating for both doctors and patients. In this regard, training for indirect ophthalmoscopy and retinal photocoagulation is undergone using model eyes instead of real eyes. Properties and functioning of an existing model eye are huge and they differ from real human eye such as casings are completely rigid and focusing of retinal fundus is not completely covered. Therefore, this research concentrates to develop a model eye that assimilates close to the human eye by focussing on the maximum viewing area that is not done at the moment. Finally, the design and development of re-engineered model eye for retina laser is fabricated by additive manufacturing. Compared to existing plastic model eye, viewing area and viewing angle of the re-engineered model eye is increased by 16.66% and 6.14%, respectively. Due to design modifications and elimination of the insert, it can be reduced by 18.99% and 13.95% of height and weight of the top casing respectively. Developed re-engineered model eye will improve the surgical and diagnostic skill of the surgeon and increase their confidence and proficiency. It also augments the effective use of essential ophthalmic instruments. Additionally, it can reduce the surgical error and meet the existing demand of actual eyes for surgical practices.

手术模拟可以提高外科医生的手术技能。尤其是在眼科领域，不可能使用真人/非人灵长类动物的眼睛进行眼科手术实践。然而，手术实践对眼科医生来说是最重要的。视网膜激光手术是眼科手术之一，外科医生需要更多的手术练习才能精确地使用激光束来凝固和融合小区域的组织。处理视力下降或视力丧失的前景是一个特殊的问题，这对医生和患者来说都是非常紧张和沮丧的。在这方面，使用模型眼代替真眼进行间接检眼镜和视网膜光凝术的培训。现有模型眼的特性和功能是巨大的，它们与真实的人眼不同，例如外壳是完全刚性的，并且没有完全覆盖视网膜眼底的聚焦。因此，本研究着眼于目前未完成的最大视域，致力于开发接近人眼同化的模型眼。最后，通过增材制造来设计和开发用于视网膜激光的重新设计的模型眼。与现有的塑料模型眼相比，重新设计的模型眼的可视面积和视角分别增加了16.66%和6.14%。由于设计修改和取消了插件，它可以分别减少顶壳的高度和重量的18.99%和13.95%。开发的重新设计的模型眼将提高外科医生的手术和诊断技能，增加他们的信心和熟练程度。它还提高了基本眼科器械的有效使用。此外，它可以减少手术错误并满足实际眼睛对手术实践的现有需求。
