Anterior vitreous face behavior with AcrySof in pediatric cataract surgery

Area of Science:

• Ophthalmology
• Pediatric Ophthalmology
• Cataract Surgery

Background:

• Cataract surgery in pediatric patients requires careful consideration of intraocular lens (IOL) placement and potential interactions with ocular structures.
• The anterior vitreous face is a critical structure in maintaining ocular integrity post-surgery.

Purpose of the Study:

• To investigate the behavior of the anterior vitreous face following AcrySof IOL implantation in pediatric cataract surgery.
• To document changes occurring when AcrySof IOLs contact the anterior vitreous face after posterior continuous curvilinear capsulorhexis without anterior vitrectomy.

Main Methods:

• The study included 14 eyes from 12 pediatric patients (mean age 9.6 years).
• All eyes underwent posterior continuous curvilinear capsulorhexis without anterior vitrectomy, with AcrySof IOLs placed in the capsular bag.
• Anterior vitreous face changes and visual acuity were monitored over a mean follow-up of 21.1 months.

Main Results:

• Anterior vitreous face changes were observed in 35.7% of eyes.
• The "anterior vitreous reticular response" (AVR) was noted in 60% of eyes with changes, characterized by a fine meshwork-like pattern.
• Younger patients (mean age 5.1 years) were more likely to develop anterior vitreous face changes compared to older patients (mean age 12.1 years) (P =.0098).
• No significant difference in visual acuity was found before and after the development of the AVR response (P =.712).

Conclusions:

• AcrySof IOLs contacting the anterior vitreous face in pediatric eyes can induce an anterior vitreous reticular response (AVR).
• This AVR response appears primarily in younger patients during the early postoperative period.
• The development of AVR does not seem to significantly affect visual acuity in these pediatric patients.
