Pediatric patients account for 35% of all cases that present after ocular trauma and 20.9% of those result in a ruptured globe. When repairing the globe, the removal of the natural lens results in a significant change in refractive error and loss of accommodation. In addition, the eye can have scarring, irregular astigmatism, and changes to the ocular surface. Treatment and vision rehabilitation should be aggressive and done quickly to prevent amblyopia. Advanced lens designs are often needed to treat both the irregular ocular surface and the aphakia. Treatment options are often confounded with the usual issues of contact lens compliance, intolerance, and complications.
This case series follows three aphakic pediatric patients through the contact lens fitting process after sustaining a ruptured globe that left them aphakic with residual irregular astigmatism and corneal scarring. Patient 1 is a 3-year-old Hispanic male fit with a bitoric gas permeable contact lens with irregular astigmatism and an elevated central corneal scarring. Patient 2 is a 12-year-old Caucasian male with minimal residual astigmatism fit in a multifocal soft contact lens. Patient 3 is an 8-year-old African American male fit with a hybrid contact lens that was needed to vault the irregular astigmatism and central corneal scarring.
Treating patients with irregular corneas or aphakia can be challenging in their own right, but in combination are some of the most advanced specialty contact lens fittings. This case series followed three pediatric patients through the fitting process and demonstrated the options and challenges when fitting this unique patient population.
小儿患者占眼外伤后就诊病例的35%,其中20.9%导致眼球破裂。修复眼球时,摘除天然晶状体可导致屈光不正显著改变和调节功能丧失。此外,眼睛可能会出现瘢痕形成、不规则散光以及眼表变化。治疗和视力康复应积极且迅速进行,以预防弱视。通常需要先进的镜片设计来治疗不规则眼表和无晶状体眼。治疗选择常常与隐形眼镜佩戴依从性、不耐受性及并发症等常见问题相互交织。
本病例系列追踪了3例无晶状体小儿患者在眼球破裂后进行隐形眼镜验配的过程,破裂导致他们无晶状体,并伴有残余不规则散光和角膜瘢痕。患者1是一名3岁西班牙裔男性,佩戴双曲面透气硬性隐形眼镜,伴有不规则散光和中央角膜瘢痕隆起。患者2是一名12岁白人男性,残余散光极小,佩戴多焦点软性隐形眼镜。患者3是一名8岁非裔美国男性,佩戴混合式隐形眼镜,以矫正不规则散光和中央角膜瘢痕。
治疗角膜不规则或无晶状体的患者本身就具有挑战性,而两者并存时则属于一些最先进的特殊隐形眼镜验配情况。本病例系列追踪了3例小儿患者的验配过程,并展示了为这一独特患者群体验配时的选择和挑战。
