Considering IOL surgery at 18 for congenital cataract (-5.25 astigmatism). Experiences?

Hey everyone,

I am 18 years old and was born with a congenital central cataract in both eyes, along with a severe astigmatism of -5.25 dpt. Since this condition has been present since early childhood, my visual system developed with it, which naturally adds some complexity to evaluating potential surgery.

My daily vision is quite challenging. In dim or indoor lighting, my vision tests at around 50 to 60 percent with my glasses. However, as soon as I go outside into bright daylight, the light hits the central cloudiness and creates a severe, blinding glare. Driving in full sunlight is extremely difficult because the brightness washes out the entire image - making my practical outdoor vision much lower than what the indoor tests show.

So far, my doctors have been cautious about recommending IOL surgery. Their hesitation is very understandable: since I grew up with this central opacity, there is a medical concern about amblyopia - meaning it is unclear how much maximum sharpness my brain can process, even with a clear artificial lens. Additionally, surgery at age 19 means losing natural accommodation. Another important factor is that my glare sensitivity has only been discussed subjectively so far; no quantitative straylight or glare test has been performed yet to measure the actual optical impact of bright light on my vision.

However, a very interesting effect happens every time my pupils are dilated with drops at the clinic. Once the pupil is wide, my distance vision transforms completely. I suddenly see crisp details, vivid color contrasts, and sharp textures in the distance that I normally cannot perceive. Since my cataract is strictly central, the wider pupil allows light to pass around the cloudy center through the clear outer edge of my natural lens.

I haven't had the chance to discuss this specific "dilation effect" with my doctor yet, as my previous appointments were quite brief. My next step is to get a second opinion at another university eye clinic, where I plan to request a quantitative glare test and discuss what this dilation effect implies for my retina's potential.

I am leaning towards surgery - ideally with toric IOLs to also address the -5.25 dpt astigmatism - because I would gladly trade natural accommodation for clear, glare-free distance vision. Has anyone here with a lifelong congenital cataract experienced a similar dilation effect? How did your doctors view the situation, and did IOL surgery help you achieve stable vision in bright light? I would really appreciate your thoughts and experiences.
